AbstractThe method of moments has been widely used in the analysis of electromagnetic scattering problems. Recently, significant advances in the development of fast and efficient techniques for solving large problems have been reported. In such methods, iterative matrix solvers are preferred by virtue of their speed and low memory requirements. But for near resonant and strong multiple scattering problems, e.g., involving an aircraft engine inlet, a large number of iterations is required for convergence. In this paper, an efficient approximate inverse based preconditioner is used to reducing this number of iterations. By using the matrix partitioning method, the computational cost for obtaining the approximate inverse is reduced to O(N). We apply this preconditioner to an O(N log N) algorithm, the multilevel fast multiple algorithm, for the aircraft engine inlet problem. The numerical results show the efficiency of this preconditioner.
