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.

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 each comprising a dielectric layer and a dielectric loss-causing layer,
- wherein said dielectric layer is positioned between said sintered ferrite tile and said dielectric loss-causing layer, said dielectric loss-causing layer comprises a lower side and an upper side, said laminates are arranged such that an upper laminate is placed directly above a lower laminate, and said dielectric loss-causing layer in said upper laminate is an uppermost dielectric loss-causing layer.
