Abstract
Conference Title: 2016 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium) Conference Start Date: 2016, June 26 Conference End Date: 2016, July 1 Conference Location: Fajardo, PR, USA 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.
