Abstract

A discontinuous Galerkin (DG) based Electric and Magnetic Current Combined-Field Integral Equation (JMCFIE) method is proposed in this paper for accurately computing electromagnetic scattering by objects with large and deep cavities. The implementation of DG allows conformal and nonconformal surface discretization, which brings significant flexibility in the meshing of large and multiscale objects. The lower triangular approximate Schur preconditioner (LTASP) is combined with Multi-Level Fast Multipole Algorithm (MLFMA) to accelerate the convergence of GMRES iteration. Numerical experiments are shown in this paper to demonstrate the accuracy and efficiency of the proposed method.
