Solution of electrically large planar scattering problems using parallel computed method of moments technique

Abstract

Parallel computations of an integral equation technique in conjunction with a Method of Moments (MoM) is introduced, in examining electromagnetic illumination of electrically large scatterers. To this end, the electromagnetic scattering of an incident wave illuminating an electrically large conducting rectangular plate of infinitesimal thickness is analyzed. An integral equation is derived in terms of the conductivity currents induced on the plate surface, which is solved by employing entire domain Galerkin technique, with Chebyshev type basis functions. The resulting algorithm parallelization enables extension of the proposed methodology above the resonance region. Numerical results are computed for several scatterer sizes and excitation source types, with significant near-linear speedups.
