You can easily get a solid, good-looking room that is full of invisible electronic leaks. Those leaks can take a long time to find and fix. We at Controlled Environment possess the knowledge necessary to make rational and intelligent management decisions regarding the design, contracting, construction, testing and maintenance of electromagnetically shielded enclosures. More Details In recent years there has been considerable progress in standardization within the Consumer Electronics, Automotive, Aero-space, Military, Medical and Telecom industries. As a result anechoic chambers today can be required to conform to a variety of different published EMC standards. In many cases the standards are so similar that the chamber does not require a set up change, in others this may require a substantial set up change. Many EMC test laboratories require their facilities to be fully compliant with as many possible EMC standards in order to offer as many tests as possible. The most common test facilities can be a compact chamber (Inner dimension 7 m by 3 m by 3 m) which can be fully compliant to Radiated Immunity tests, or the 3m semi-anechoic chamber (Inner dimension 9 m by 6 m by6 m) which is fully compliant to Radiated Immunity andEmissions. There is also an anechoic chamber which can measure electric waves emitted from electronic equipment. Electromagnetic shielded rooms are surrounded on six sides (floor, walls, ceiling) by conductive materials (iron, copper, etc.), and the equipment is subjected to shield-piercing processing. The anechoic chamber is an electromagnetic shielded room whose surface is attached with an electromagnetic wave absorber. Depending on the measuring distance, there are three-meter and ten-meter electric wave darkrooms among others. Precision installation provides excellent performance of test facilities to meet NSA 65-6 R.F. Shielded enclosures for communication equipment, IEC 1000-4-3 Uniformity and ANSI C 63.4 Site Attenuation. We provide the best Shielded Room and Anechoic chamber meeting International Standards at reasonable price. Prompt delivery and excellent service. Electromagnetic shielded buildings and rooms have been developed to prevent damage to equipment caused by electromagnetic waves and to prevent the "leakage" from a building of electric wave signals that could be intercepted. 1. In the area of electromagnetic shields, shielded room kits (panel-assembling type) have been developed for semiconductor plants and research facilities which sometimes require high shielding capacity. Effective shielding at 10-30KHz is 60 decibels or greater, while it is 100 decibels or greater at frequencies of 30KHz-1GHz. 2. In the area of magnetic shields, we have developed a high-performance shielded room for SQUID sensors which can measure trace magnetivity (1/100,000,000 that of the earth) which is emitted by living organisms. 3. The integrated construction and installation of the buildings and shielded facilities help to reduce the time needed to complete setup. Your continued donations keep Wikipedia running! Electromagnetic shielding From Wikipedia, the free encyclopedia Jump to: navigation, search Electromagnetic shielding is the process of limiting the flow of electromagnetic fields between two locations, by separating them with a barrier made of conductive material. Typically it is applied to enclosures, separating electrical devices from the 'outside world', and to cables, separating wires from the environment the cable runs through. Electromagnetic shielding used to block radiofrequency electromagnetic radiation is also known as RF shielding. The shielding can reduce the coupling of radio waves, visible light, electromagnetic fields and electrostatic fields, though not static magnetic fields. (A conductive enclosure used to block electrostatic fields is also known as a Faraday cage.) The amount of reduction depends very much upon the material used, its thickness, and the frequency of the fields of interest. Contents [hide] 1 Materials used 2 Example applications 3 How RF shielding works 4 See also 5 External links Materials used Typical materials used for electromagnetic shielding include sheet metal, metal mesh, ionized gas, and plasma. Any holes in the shield or mesh must be significantly smaller than the wavelength of the radiation that is being kept out, or the enclosure will not effectively approximate an unbroken conducting surface. Another commonly used shielding method, especially with electronic goods housed in plastic enclosures, is to coat the inside of the enclosure with a metallic ink or similar material. The ink consists of a carrier material loaded with a suitable metal, typically copper or nickel, in the form of very small particulates. It is sprayed on to the enclosure and, once dry, produces a continuous conductive layer of metal, which can be electrically connected to the chassis ground of the equipment, thus providing effective shielding. Example applications One example is a shielded cable, which has electromagnetic shielding in the form of a wire mesh surrounding an inner core conductor. The shielding impedes the escape of any signal from the core conductor, and also signals from being added to the core conductor. Some cables have two separate concentric screens, one connected at both ends, the other at one end only, to maximise shielding of both electromagnetic and electrostatic fields. The door of a microwave oven has a screen built into the glass of the window. From the perspective of microwaves (with wavelengths of 12 cm) this screen finishes a Faraday cage formed by the oven's metal housing. Visible light, with wavelengths ranging between 400nm and 900nm, passes easily between the wires. RF shielding is also used to prevent access to data stored on RFID chips embedded in various devices, such as biometric passports. How RF shielding works Electromagnetic radiation consists of coupled electric and magnetic fields. The electric field produces forces on the charge carriers (i.e., electrons) within the conductor. As soon as an electric field is applied to the surface of an ideal conductor, it generates a current that causes displacement of charge inside the conductor that cancels the applied field inside, at which point the current stops. Similarly, varying magnetic fields generate current vortices that act to cancel the applied magnetic field. (The conductor does not respond to static magnetic fields, so static magnetic fields can penetrate the conductor freely.) The result is that electromagnetic radiation is reflected from the surface of the conductor: internal fields stay inside, and external fields stay outside. Several factors serve to limit the shielding capability of real RF shields. One is that, due to the electrical resistance of the conductor, the excited field does not completely cancel the incident field. Also, most conductors exhibit a ferromagnetic response to low-frequency magnetic fields, so that such fields are not fully attenuated by the conductor. Any holes in the shield force current to flow around them, so that fields passing through the holes do not excite opposing electromagnetic fields. These effects reduce the field-reflecting capability of the shield. In the case of high-frequency electromagnetic radiation, the above-mentioned adjustments take a non-negligible amount of time. But then the radiation energy, as far as it is not reflected, is absorbed by the skin (unless it is extremely thin), so in this case there is no electromagnetic field inside either. This is called the skin effect. A measure for the depth to which radiation can penetrate the shield is the so-called skin depth.

This description was originally used in the context of acoustic (sound) echoes caused by reflections from the internal surfaces of the room but more recently the same description has been adopted for the radio frequency (RF) anechoic chamber. An RF anechoic chamber is designed to suppress the electromagnetic wave analogy of echoes: reflected electromagnetic waves, again from the internal surfaces. Both types of chamber are normally constructed, not only with echo suppression features, but also with effective isolation from the acoustic or RF noise present in the external environment. In a well designed acoustic or RF anechoic chamber the equipment under test will only receive signals (whether acoustic or RF) which were emitted directly from the signal source, and not reflected from another part of the chamber. 1 The Acoustic Anechoic Chamber 2 The Radio Frequency Anechoic Chamber 2.1 Radiation Absorbent Material 2.2 Effectiveness over Frequency 2.3 Installation into a Screened Room 2.4 Chamber Size and Commissioning 2.5 Operational Use 2.6 The Health and Safety Risks associated with the RF Anechoic Chamber 3 External links The Acoustic Anechoic Chamber Acoustic anechoic chambers are used for measuring the acoustic properties of musical instruments, determining the transfer functions of electro-acoustic devices, testing microphones and other audio equipment and performing psychoacoustics experiments (such as measuring the quality of audio codecs or measuring head-related transfer functions). Echoes are surpressed within the chamber by the installation of acoustically absorptive material covering all of the internal surfaces. Attenuation of echoes in this way also greatly reduces reverberation. To the human ear acoustic anechoic chambers have the characteristic of being muted, muffled, and silent. Most acoustic anechoic chamber tests are also susceptible to acoustic noise penetrating the chamber from the external environment. This is minimised using sound proofing or acoustic isolation which may be achieved by encasing the chamber in a shell of dense, highly absorptive material such as cement, typically about a metre thick. The chamber may also provide additional isolation by being a completely independent shell mounted on rubber shock absorbers inside another room with no connections between them other than for essential services such as cables. Anechoic chambers, modeled after the world's first wedge-based anechoic chamber at Murray Hill, Bell Labs, typically use fiberglass wedges (Anechoic tile) on the internal surfaces to absorb incident sound waves. The wedge shapes act as a waveguide to focus incoming sound into the fiberglass wedge, where the acoustic energy is converted to heat. The alternating pattern is used to achieve a more uniform angular absorption. Frequencies below about 200 Hz are not as effectively absorbed by the wedges. Anechoic chambers in which the bottom is also composed of wedges have the floor formed by a wire mesh suspended above the bottom by wires. Other anechoic chambers only use wedges for five of the six sides of the room. John Cage, a 20th century composer, cited his experience in 1951 in Harvard University's anechoic chamber, a room in which he expected to hear nothing, but heard instead what was believed to be the sound of his own bloodflow and nervous system as the inspiration for his famous "silent" composition, 4' 33". We build test labs and test laboratories. Anechoic-chamber technology is also used in soundproofing and sound proofing rooms for indoor shooting ranges, and for hearing aid test chambers. The Radio Frequency Anechoic Chamber The internal appearance of the radio frequency (RF) anechoic chamber is sometimes similar to that of an acoustic anechoic chamber, however, the interior surfaces of the RF anechoic chamber are covered with radiation absorbent material (RAM) instead of acoustically absorbent material [1]. The RF anechoic chamber is typically used to house the equipment for performing measurements of antenna radiation patterns, electromagnetic compatibility (EMC) and radar cross section measurements. Testing can be conducted on full-scale objects, including aircraft, or on scale models where the wavelength of the measuring radiation is scaled in direct proportion to the target size. Coincidentally, many RF anechoic chambers which use pyramidal RAM also exhibit some of the properties of an acoustic anechoic chamber. Radiation Absorbent Material The RAM is designed and shaped to absorb incident RF radiation, also known as non-ionising radiation as effectively as possible from as many incident directions as possible. The more effective the RAM is the less will be the level of reflected RF radiation. Many measurements in electromagnetic compatibility (EMC) and antenna radiation patterns require that spurious signals arising from the test setup, including reflections, are negligible to avoid the risk of causing measurement errors and ambiguities. One of the most effective types of RAM comprises arrays of pyramid shaped pieces, each of which is constructed from a suitably lossy material. To work effectively, all internal surfaces of the anechoic chamber must be entirely covered with RAM. Sections of RAM may be temporarily removed to install equipment but they must be replaced before performing any tests. To be sufficiently lossy, RAM can neither be a good electrical conductor nor a good electrical insulator as neither type actually absorbs any power. It has to be an intermediate grade of material which absorbs power gradually in a controlled way as the incident wave penetrates it. Typically pyramidal RAM will comprise a rubberised foam material impregnated with controlled mixtures of carbon and iron. An alternative type of RAM comprises flat plates of ferrite material, in the form of flat tiles fixed to all interior surfaces of the chamber. This type is more narrow band than the pyramidal RAM and is designed to be fixed to good conductive surfaces. It is generally cheaper, easier to fit and more durable than the pyramidal type RAM but is less effective at lower frequencies. Its performance might however be quite adequate if tests are limited to the higher RF or microwave frequencies. Effectiveness over Frequency The performance quality of an RF anechoic chamber is determined by its lowest test frequency of operation, at which measured reflections from the internal surfaces will be the most significant compared to higher frequencies. Pyramidal RAM is at its most absorptive when the incident wave is at normal incidence to the internal chamber surface when the pyramid height is approximately equal to 4, where is the free space wavelength. Accordingly, increasing the pyramid height of the RAM for the same (square) base size improves the effectiveness of the chamber at low frequencies but results in increased cost and a reduced unobstructed working volume that is available inside a chamber of defined size.. Installation into a Screened Room An RF anechoic chamber is usually built into a screened room, designed using the Faraday cage principle. This is because most of the RF tests that require an anechoic chamber to minimise reflections from the inner surfaces also require the properties of a screened room to: attenuate unwanted signals penetrating inwards and causing interference to the equipment under test prevent leakage from tests penetrating outside Chamber Size and Commissioning The actual test setups usually require extra room than that required to simply house the test equipment, the hardware under test and associated cables. For example, the far field criteria sets a minimum distance between the transmitting antenna and the receiving antenna to be observed when measuring antenna radiation patterns. Allowing for this and the extra space that may be required for the pyramidal RAM means that a substantial capital investment is required into even a modestly dimensioned chamber. For most companies a such an investment in a large RF anechoic chamber is not justifable unless it is likely to be used continuously or perhaps rented out. Sometimes for radar cross section measurements it is possible to scale down the objects under test and reduce the chamber size provided that the wavelength of the test frequency is scaled down in direct proportion. RF anechoic chambers are normally designed to meet the electrical requirements of one or more accredited standards. Once built, acceptance tests are performed during commissioning to verify that the standard(s) are in fact met. Provided they are, a certificate will be issued to that effect, valid for a limited period. Operational Use Test and supporting equipment configurations to be used within anechoic chambers must expose as few metallic (conductive) surfaces as possible, as these risk causing unwanted reflections. Often this is achieved by using non-conductive plastic or wooden structures for supporting the equipment under test. Where metallic surfaces are unavoidable, they may be covered with pieces of RAM after setting up to minimse such reflection as far as possible. A careful assessment of whether to place the test equipment (as opposed to the equipment under test) on the interior or exterior of the chamber is required. Normally this may be located outside of the chamber provided it is not susceptible to interference from exterior fields which, otherwise, would not be present inside the chamber. This has the advantage of reducing reflection surfaces inside but it requires extra cables and particularly good filtering. Unnecessary cables and/or poor filtering can collect interference on the outside and conduct them to the inside. A good compromise may be to install human interface equipment (such as PCs), electrically noisy and high power equipment on the outside and sensitive equipment on the inside. One useful application of fiber optic cables is to provide the communications links to carry signals within the chamber. Fiber optic cables are non-conductive and of small cross-section and therefore cause negligible reflections in most applications. It is normal to filter electrical power supplies for use within the anechoic chamber as unfiltered supplies present a risk of unwanted signals being conducted into and out of the chamber along the power cables. The Health and Safety Risks associated with the RF Anechoic Chamber The following health and safety risks are associated with RF anechoic chambers: RF radiation hazard Fire hazard Trapped personnel Personnel are not normally permitted inside the chamber during a measurement as this can not only cause unwanted reflections from the human body but may also be a radiation hazard to the personnel concerned if tests are being performed at high RF powers. Such risks are from RF or non-ionising radiation and not from the higher energy ionising radiation. As RAM is highly absorptive of RF radiation, incident radiation will generate heat within the RAM. If this cannot be dissipated adequately there is a risk that hot spots may develop and the RAM temperature may rise to the point of combustion. This can be a risk if a transmitting antenna inadvertently gets too close to the RAM. Even for quite modest transmitting power levels, high gain antennas can concentrate the power sufficiently to cause high power flux near their apertures. Although recently manufactured RAM is normally treated with a fire retardant to reduce such risks, they are difficult to completely eliminate. Safety regulations normally require the installation of a gaseous fire suppression system including smoke detectors. Gaseous fire suppression avoids damage caused by the extuinghishing agent which would otherwise worsen damage caused by the fire itself. A common gaseous fire suppression agent is carbon dioxide. Normally the fire detection system is linked into the power supply to the chamber arranged to disconnect it if smoke or a fire is detected.
