Overview
The anechoic chamber or shielded enclosure is lined with absorbing material, which can absorb
electromagnetic waves and reduce or eliminate the reflection and scattering of radio waves. The
performance of the anechoic chamber is closely related to the absorbing performance, frequency
band characteristics, shape, thickness and type of the absorbing material. The more electromagnetic
waves absorbed by absorber, the smaller the reflection, so that the surrounding environment is
getting closer to free space, and the performance of the anechoic chamber is better.
Absorbing materials include polyurethane foam, polystyrene, rubber and other materials. Select the
size, shape and material of the RF absorber according to the size and application of the anechoic
chamber or shielded enclosure. It is also necessary to consider the absorbing performance, frequency
band, price and weight of the RF absorber.
