Microwave absorbers or Radiation Absorbent Materials-RAM 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, and hybrid dielectric absorber, among others. This paper presents a new concept for RAMs applying corrugated surfaces to…
