ABSTRACT:
A wave absorber comprising a sintered ferrite tile wave absorber as a base substrate lowermost relative to the incident wave, and one or more laminates comprising two layers as one set, with a dielectric layer as a lower layer and a dielectric loss-causing layer as an upper layer, laminated on the base substrate. The wave absorber of the present invention is thin, but is capable of absorbing waves over wide frequency bands of from tens of megahertz to a dozen or so gigahertz. By making the absorber thin, the absorber weighs less and is easy to handle, which in turn leads to fine workability and low construction cost.
