Scattering by large, complex, composite targets using hybrid FE/BI/MLFMA

Computation of scattering by large, complex, composite targets is one of most challenging problems in computational electromagnetics (CEM). A formulation of hybrid FE/BI/MLFMA is presented for this kind of problem. The numerical performance of the hybrid FE/BI/MLFMA is investigated by computation of a conducting sphere coated with anisotropic material and a conducting brick with deep material-filled cavity.
