| Abstract: | 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. |
