EMC Absorbers are the materials which are used to absorb the electro-magnetic radiation emitted by Electronic / electrical devices. EMC absorbers are commonly used in Anechoic chamber for radiated emission testing of euipment. EMC Absorbers from the leading manufacturers are listed below.

EMC Absorbers are used in an enclosed room to reduce the reflection of EM waves. These absorbers are made of such material which helps them to absorb the EM waves to give precise and repeatable test conditions for EMC (Electromagnetic Compatibility) and antenna measurements. The absorbers are given desired shape and size to suit the frequency range of the EMC testing. Many EMC testing sites prefer pyramidal-shaped absorbers. The tapered top part of the absorber allows the EM wave to reflect and gradually absorb as they penetrate.
There are two main categories of absorbers:
EMC absorbers are made of various materials such as carbon-impregnated low-density Polyurethane foam, ferrite, etc. to provide excellent performance in normal incidence and off-angle incidence in an Anechoic chamber with a desirable impedance matching. These absorbers are usually weatherproof and leakproof (leakage of carbon particles) during their life cycle to provide a clean working laboratory.
