Abstract

In this letter, an efficient solution based on the modal expansion method for the analysis of wave scattering from multiple arbitrary circular cavities placed in a perfect electric conductor is presented. Unlike most of the existing methods that employ the Graf's addition theorem, which brings serious problems, we employ the complex function method cooperating with multipolar coordinate transformation to match tangential fields in analyzed regions. Finally, unknown expansion coefficients are computed by solving the system of linear equations and the Fourier series. Some typical examples are given to verify the solution by the method of moments.

PEC平面上加载多个任意圆腔的散射

本文提出了一种基于模态展开法分析理想电导体中任意多个圆腔波散射的有效解。不同于大多数利用Graf加法定理的方法所带来的严重问题，我们采用配合多极坐标变换的复函数方法来匹配分析区域的切向场。最后，通过求解线性方程组和傅里叶级数计算未知膨胀系数。给出了一些典型的算例来验证矩量法的解。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
