Abstract :
In this paper, multilevel fast multipole algorithm (MLFMA) with curvilinear RWG basis is used to realize fast, accurate solution of electromagnetic scattering from 3-D conducting object. This method needs much less unknowns than traditional RWG basis and conformal rooftop basis, is especially appropriate for efficient solution of scattering from target with large electrical sizes. Numerical results are given to demonstrate the validity and efficiency of the present method.
