    • 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.
    • 一种波形吸收体,其特征在于,包括作为基底基板的烧结铁氧体磁阻波浪吸收体相对于入射波最低的一个波长吸收体,以及一个或多个层叠体,其包含两层作为一组,其中介电层为下层,介电损耗层为 上层,层压在基底上。 本发明的吸波体较薄,但能够在数十兆赫兹到十几千兆赫兹的宽频带上吸收波。 通过使吸收体变薄,吸收体重量少,易于处理,反而导致加工性能好,施工成本低。
