Abstract
A general hybrid finite-element/boundary-integral/multilevel fast multipole algorithm (FE/BI/MLFMA) is presented for computation of scattering by large complex targets. Various algorithms of the hybrid FE/BI/MLFMA are presented and compared heuristically and numerically in this paper. The accuracy and iterative convergence speed of these algorithms are investigated in detail. Furthermore, the presented asymmetric formulation of the hybrid FE/BI/MLFMA in this paper is compared, from the point of the generality and efficiency views, with the symmetric FE/BI/MLFMA formulation recently proposed by other authors. A general, accurate, and efficient code based on an efficient algorithm of the hybrid FE/BI/MLFMA is developed for large complex targets. The scattering by several large complex targets is computed at last in this paper.
