摘 要: | 本文提出了一种有效降低矩量法分析对称电磁模型计算复杂度的方法。通过对激励向量[ V]的分解和重组,使得几何对称结构具有对称的电流分布,从而只需对一部分电流进行求解,大大减少了未知量数目。数值仿真实例验证了所提出方法的有效性与精确性。

A Simplification Method for Symmetrical Model in Computational Electromagnetics |
| |
Abstract: | In this paper,a new and efficient simplificationmethod for symmetry model in computational e-lectromagnetics(CEM) is presented. The numerical method used in this paper is Method of Moments ( MOM) . We can make the induced currentdistribution of a symmetry structure symmetrical bydecompos-ing and restructuring the excitation vector [ V] ,so thatonly a part of the induced current needs to be cal-culated. Consequently,compared to modeling of the whole structure,thesimplification method provides a drastic reduction of unknowns,which saves much more memory resources and computation time. Numeri-cal examples show the reliability and accuracy of theproposed method. |
