Title: ELECTROMAGNETIC WAVE ABSORBER AND METHOD FOR PRODUCING ELECTROMAGNETIC WAVE ABSORBER
Abstract:
This electromagnetic wave absorber is equipped with: a support body; a plate-shaped first electromagnetic wave absorbing layer which contains an electromagnetic wave absorbing material and a binder, and is positioned on the surface of the support body; a second electromagnetic wave absorbing layer which is provided so as to stand upright on the surface of the first electromagnetic wave absorbing layer, contains an electromagnetic wave absorbing material and a binder, constitutes cone-shaped projections which contact one another at the outer-circumferential sections of the floor surfaces thereof, and is configured in a manner such that the distance between peaks of adjacent cone-shaped projections is 0.5-λamm, inclusive, given that the wavelength of the absorbed electromagnetic waves is λa. Also provided is a method for producing this electromagnetic wave absorber.
