A sweeping preconditioner for Yee＇s finite difference approximation of time-harmonic Maxwell＇s equations

这份报纸涉及在 electromagnetics 从有限差别 discretizations 产生的线性系统的快反复的解决方案。有以前为 Helmholtz 方程开发的动人的完美地匹配的层的大规模 preconditioner 在不同类的、各向异性的媒介为波浪繁殖为流行 Yee 格子计划被改编。初步的数字结果为典型例子被介绍。

This paper is concerned with the fast iterative solution of linear systems arising from finite difference discretizations in electromagnetics. The sweeping preconditioner with moving perfectly matched layers previously developed for the Helmholtz equation is adapted for the popular Yee grid scheme for wave propagation in inhomogeneous, anisotropic media. Preliminary numerical results are presented for typical examples.
