提出了一种基于阻抗矩阵归一化的新型基函数,其构造过程简单易行、计算量和内存需求少且构造过程具有普适性.通过计算实例表明,基于RWG基函数的阻抗矩阵归一化基函数有效地改善了具有边缘、尖顶、精细结构理想导体目标电场积分方程矩量法的阻抗矩阵条件数、显著地降低了阻抗矩阵方程迭代法求解的迭代次数.

Method of moments of the surface integral equations based on the impedance-matrix-normalized basis functions

This paper presents a novel impedance matrix normalized basis functions (IMNBFs), which can be designed simply and easily. The method to construct MNBFs is general and constructed procedure needs little computational costs. The IMNBFs based method of moments (MoM) of the electric field integral equations trends to produce well conditioned impedance matrix, when non uniform meshes need to discretize perfectly electric conductive (PEC) objects with edges or tips or fine structures, thus convergence of iterative solvers for matrix equations is accelerated obviously.
