摘要:
In this paper, adaptive integral method (AM combined with a novel preconditioner scheme mesh neighbor (MN) preconditioner is applied to the scattering analysis of arbitrarily shaped planar structures. Using AIM the RWG basis functions are translated onto a rectangular grid then fast Fourier transform is invoked to compute the matrix-vector products in the iterative solver. The algorithm has a memory requirement and computation complexity proportional to O(N) and O(N log N), respectively M-preconditioner is applied to improve the convergence of iterative solvers. The numerical results are presented to show the efficiency and accuracy of the proposed method.
