摘要

This paper presents a new flexible GMRES for solving surface integral equation (SIE). In the proposed method, JMCFIE is set as the inner iteration to accelerate the convergence speed, while PMCHWT is set as the outer iteration to guarantee the accuracy. In addition, multilevel fast mutilpole algorithm (MLFMA) is used to reduce the memory of impedance matrix and improve the computational efficiency. The method is validated by comparisons with the analytic Mie solution and the conventional flexible GMRES, to illustrate the accuracy and high efficiency, respectively.
