Microwave absorbers are normally made of blocks of wave-absorptive material to avoid the reflection of electromagnetic waves incidental on it. Mainly used in anechoic chambers, it comes in various designs such as pyramidal absorber, twisted pyramidal absorber, hollow pyramidal absorber, wedge absorber, multilayer dielectric absorber, hybrid dielectric absorber, walkway absorber, and convoluted microwave absorber. Nowadays, most of the electromagnetic anechoic chamber manufacturers offer a standard microwave absorber product that is pyramidal in shape , which could meet specified industrial standards.
