| 摘 要： | 基于电场的矢量Helmholtz方程,提出了一种分析二维导体柱散射的高效算法;给出了二维导体柱边界条件的电场矢量差分方程,以及用于计算导体表面电流的电场矢量差分表达式;采用了二阶Mur's吸收边界条件和场平均吸收条件截断网格.用所提方法分析了无限长理想导体方柱对平面电磁波的散射,其结果与矩量法的吻合很好.

| Abstract: | Based on the vector Helmholtz equation of electric field,an efficient numerical method is presented for the analysis of two-dimensional conducting cylinder scattering.The electric field finite difference equations of the two-dimensional conducting cylinder boundary conditions are derived as well as those of the surface current.The Mur's absorbing boundary conditions(ABCs)of the second order and the ABCs based on the field average are applied at the truncation boundary nodes.The scattering from two-dimension... |
