SSOR Preconditioned Flexible GMRES Method For MLFMM Analysis of EM Scattering Problems
To efficiently solve large dense complex linear system arising from electric field integral equations (EFIE) formulation of electromagnetic scattering problems,the multilevel fast multipole method (MLFMM) is used to accelerate the matrixvector product operations.The flexible generalized minimum residual method (FGMRES) is combined with the symmetric successive over-relaxation (SSOR) preconditioner based on the near-part matrix of the EFIE in the inner iteration of FGMRES to speed up the convergence rate of iterative methods.Numerical experiments with a few electromagnetic scattering problems for open structures are given to demonstrate the efficiency of the proposed method.
