Abstract

This paper aims to develop a fast and robust algorithm for three-dimensional problems, especially for large-permittivity case. We adopt the generalized minimum residual (GMRES) and loose GMRES to replace the CG or BCG method to solve the integral equation, and investigate their efficiency in the application. We show that all methods produce accurate results and when the contrast is high, the loose GMRES has a superior behavior among the different iterative methods
