Abstract
A multi layer electromagnetic wave absorber is provided. The absorber includes a surface layer comprising at least one of a dielectric lossy mixture and a magnetic lossy mixture, an absorption layer, laminated on a rear side of the surface layer, comprising: a dielectric lossy mixture having a higher loss than the dielectric lossy mixture for the surface layer, and a magnetic lossy mixture having a higher loss than the magnetic lossy mixture for the surface layer, and a boundary layer, laminated on a rear side of the absorption layer, comprising a conductive material.
