Broadband radio-absorbing coatings

摘要

Wideband radar absorbing coating made in the form of the absorbing layer of a material with a dielectric constant ε = ε '+ i · ε' ', magnetic permeability μ = μ' + i · μ '' and the index n of refraction deposited onto the reflective electromagnetic wave surface, characterized in that the absorbing layer is made of a material having a real part of the square of the refractive index is less than zero.
