利用保角变换方法,将奇异性边界变换为简单光滑的边界,从而使点匹配法计算表面电流时能自动控制边界的划分和匹配点的选取,因而它能处理任意截面导电柱体的散射问题。本文进一步将保角变换方法与互易定理结合起来,这一方法可以处理任意截面柱体旁天线辐射的一般问题。本文计算了无限长正四棱柱对平面波的散射并与圆柱的散射进行了比较;并计算了无限长导电正四棱柱分周向半波振子的辐射并用矩量法的结果进行了验证。
Conformal mapping method is used to transform the singularity boundary into a simple and smooth boundary, so that the point matching method can automatically control the division of the boundary and the matching point when calculating the surface current, so it can deal with the scattering problem of the conductive pillar with arbitrary cross section . In this paper, the conformal transformation method and the reciprocity theorem are further combined. This method can deal with the general problems of antenna radiation near the arbitrary column cylinder. In this paper, the scattering of plane wave by an infinite regular quadrangular prism is calculated and compared with that of the cylindrical scattering. The radiation of an infinitely long conductive quadrupole is calculated by the method of moment method.
