Abstract

In this paper, we investigate some matrix preconditioning techniques for handling highly ill-conditioned matrices that often arise in Computational Electromagnetics (CEM). A preconditioning technique based on the use of Singular Value Decomposition (SVD) is proposed in this work to speed up the convergence of iterative methods when handling such matrices. Following this we review the Characteristic Basis Function Method (CBFM) and compare it to the preconditioner approach to handle similar problems.
