Abstract

Efficient and accurate solution of electromagnetic boundary value problems involving electrically-large and geometrically complex objects continue to challenge us, because they present a heavy burden on the CPU time and memory. During recent years, various domain decomposition schemes that are based on iterative techniques have been proposed to solve large-scale electromagnetic scattering problems by partitioning the original problem into smaller and manageable subproblems [1-4].
