摘要 稀疏矩阵规则网格(SMCG)法,是一种有效的电磁场数值计算方法。为了进一步提高SMCG方法的计算效率,文章提出了两种预处理SMCG方法,并应用这两种方法对随机分布三维介质多目标的电磁散射特性进行了分析。数值计算表明,该方法是快速、有效的。 <Abstrcat>The sparse matrix canonical grid method(SMCG) is an effective numerical method for analyzing electromagnetic fields. Two preconditioned SMCG methods are proposed in this paper to further improve computational efficiency. The presented methods are used to analyze electromagnetic scattering from three-dimensional multiple random dielectric scatterers. The far scattered fields of several examples are calculated. It is shown that the presented methods are fast and effective.
