Abstract

An edge-based finite element formulation with conformal absorbing boundary conditions (ABCs) is presented for scattering by composite three dimensional structures having boundaries satisfying impedance and/or transition conditions. The methodology with its O(N) storage requirement is amenable to large-scale parallelization. Tests have been carried out on a massively parallel architecture with impressive speedups
