摘要
利用矩量法对圆柱导体电磁散射特性进行了研究。基于伽略金法,采用分域基函数展开模式,得出了圆柱导体的电磁散射方向图,并对圆柱体直径和入射波波长不同比例情况下的散射情况进行了研究。文中还用MATLAB给出了圆柱体电磁散射的精确计算结果。
In this paper, the EM scattering characteristics from a conductive cylinder by using the method of moment. Based on Galerkin＇s method, Maxwell equations are transformed into matrix equations by using piece wise function as the expansion and testing functions. The effect of cylinder＇ s diameter and wavelength is analyzed and the numerical results are presented by using MATLAB.
