Electromagnetic absorbers
Electromagnetic absorbers are specifically chosen or designed materials that can inhibit the
Generally, there are two types of absorbers: resonant absorbers and broadband absorbers. The resonant absorbers are frequency-dependent because of the desired resonance of the material at a particular wavelength. Different types of resonant absorbers are the Jaumann absorber, the Dallenbach layer, crossed grating absorbers, and circuit analog (CA) absorbers.
Broadband absorbers are independent of a particular frequency and can therefore be effective across a broad spectrum.[4]
