摘要
对频率选择表面 (FSS)在复合吸波材料设计中的应用进行了研究 .把具有不同几何图案的FSS置于多层复合吸波材料中的不同位置 ,得到多个不同的样品 ,并在以HP872 2ES矢量网络分析仪为核心的弓形法测试系统中进行微波吸收性能测量 .测试结果表明 :FSS的存在显著影响复合吸波材料的吸收性能 ;FSS的图案、几何尺寸以及在复合结构中的位置都对样品的反射率特性产生影响 .优化FSS在复合吸波材料中的使用可获得频带较宽、吸波性能较强的复合吸波材料 .
Study on the application of frequency selective surface (FSS) to the design of composite microwave absorbers was presented. Microwave absorbing performance was tested by the Arch measurement system based on the HP8722ES vector network analyzer. A series of samples could be fabricated by embedding FSS with different types of pattern in different position of multiplayer composite absorbing media. The measurement results showed that absorbing performance of absorbers was influenced by FSS. Its features such as pattern, size and location in the composite were critical for the reflectivity of the samples. The optimization of the application of FSS to the design of composite microwave absorbers could widen the frequency range and increase the absorbing ability.
