多层频率选择表面的分析

本文利用矩量法和广义散射矩阵理论分析了多层频率选择表面的散射特性。通过引入广义波导概念,可以统一分析单元形状为任意的多层频率选择表面。作为示例,计算了几种不同结构频率选择表面的散射特性,结果与文献中给出的数据相符。

Analysis of Multilayer Frequency-Selective Surfaces

In this paper, the scattering characteristics of a plane wave incident on multilayered frequency-selective surfaces (FSSs) are analyzed by the method of moments combined with generalized scattering matrix theory. By introducing an idea of generalized waveguide, a unified treatment of multilayer FSSs with element of arbitrary shape is realised. As examples, the scattering characteristics of several structures are computed. Numerical results show good agreement with those published in literatures.
