Investigation of the Attenuation Properties of a Compact Absorber Based on a Metamaterial and a Nanometer Conductive Film

We present a comparison of experimental and theoretical studies of combined radar-absorbing coatings. Multilayer structures were formed on solid metal-dielectric substrates., for which an experimental study of their frequency dependences was carried out. The resulting scattering diagrams for the combined surface and its individual components are compared with numerical models. A comparative analysis of the modeling and experimental results of weakening multilayer structures is given.
