摘要
介绍了等效电路法(equivalent circuit method,ECM)在频率选择表面(frequency selective surfaces,FSS)中的研究及应用,阐述了用ECM分析计算FSS阵列传输特性的基本过程以及几种常用FSS单元的等效电路模。仿真计算了双方环贴片型单元FSS阵列的双频带阻特性,并与前人的试验结果做了对比。比较结果表明,用ECM分析双带FSS的传输特性是可行的。最后,用ECM仿真分析了双方环缝隙型单元的双带通特性。
The equivalent circuit method （ECM） is introduced in the research and application of frequency selective surfaces （FSS）. The basic process of analyzing FSS with ECM is expatiated. The equivalent circuit models of some general elements are presented. The double stopband performance of the double square patch element is computed and the conclusion is compared with the experiment results obtained by the predecessors. And then the feasibility of analyzing dual-band FSS by using the equiralent circuit method is approved. In addition, the double passband properties of double square slot element is simulated by ECM.
