In this paper, the IE-FFT has been successfully implemented with the curvilinear basis function to solve scattering problems. The IE-FFT is used to speed up the matrix-vector multiplication. The CPU time per iteration is O(N1.5log(N)) and the memory requirement is O(N1.2). The MN preconditioner has been used to improve the convergence of the CG solver and the good performance has been shown. The speed...
In this paper, MLFMA is implemented in the IEFIE to compute scattering from complex conducting structure coated by thin dielectric material. Numerical results demonstrate the efficiency and validity of the present method.
