摘要

提出了一种研究不同栅格及单元外形并有介质加载的双层频率选择表面(FSS)电性能的理论分析方法.通过确定双层FSS之间介质内传输波和反射波分别对相应的FSS具有周期性而得到矢量Floquet传输模和衰减模表达形式

应用切向电磁场边界条件推导出一组耦合积分方程

利用矩量法求解得到结构的电磁特性.以Y形缝隙作为FSS谐振单元

计算结果表明

双层FSS结构通过层间电磁场衰减模的耦合能够修正频率响应曲线

电性能较单层有很大的改善.

Abstract

A theoretical approach analyzing electrical performance for dielectric loaded dual-layer Frequency Selective Surface (FSS) configuration with dissimilar lattice and element geometries is proposed.The forward and reverse waves are periodic with corresponding FSS respectively

and an explicit description of vectorial propagation as well as of evanescent modes is provided.A group of coupled integral equations is derived by applying tangential electromagnetic field boundary conditions

and electromagnetic properties can be obtained by moment method.Calculation results show that

dual-layer configuration can shape frequency response curves because of the coupling of evanescent modes between FSSs

and electrical performance has great improvements as compared with single-layer configuration.
