摘要
利用拱形法对制备出的由频率选择表面(FSS)和两层吸波材料组成的夹层复合结构吸波材料的吸波效能进行了测试,研究了频率选择表面对复合吸波材料吸波效能的影响。结果表明:频率选择表面的加入改变了吸波材料的工作频段,拓宽了吸波材料的带宽,并且频率选择表面单元尺寸和电磁波入射角度不同,对其吸波效能的影响也不同。
Arch test method is used to measure the absorbing efficiency of multilayer absorbing material composed by two single-layer absorbers sandwiched by frequency selective surface（FSS）,and the influence of the FSS on absorbing efficiency of composite material is studied. Measurement results show that the introducing of FSS changes the absorbing frequency range and expands the bandwidth of absorbing material. Furthermore, the FSS element with different sizes and incident angles of electromagnetic wave could yield different results.
