Abstract

The goal of this paper is to propose a simple and efficient preconditioning technique based on optimal choice of weights of basis functions, which significantly improves the convergence of iterative solvers applied to surface integral equations (SIE). The significant improvement is demonstrated using the conjugate gradient method (CGM) applied to electric field integral equations (EFIE) and Poggio-Miller-Chang-Harrington-Wu (PMCHW) equations.
