Basic Functions in MoM for Solving 2D EM Scattering Problems

针对横截面为正方形的散射柱,根据二维对称物体的对称特点构造群,通过群变换方法求得该群的分类基,将该分类基应用于矩量法并求解二维散射问题.

According to the symmetric feature of a scattering cylinder whose cross section is square,classified basis functions can be obtained by means of the group theory.This paper shows a new way to obtain the basic functions used in MoM for solving EM sacttering problems with complicated symmetric boundaris.
