Scalability of parallel processing method of moments technique in treating electrically large electromagnetic structures

Electromagnetic scattering by electrically large planar conductors is examined, by employing parallel computations of an integral equation technique in conjunction with a method of moments (MoM). The integral equation in terms of the conductivity currents induced on the plate surface is solved using 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 with impressive near-linear speedups, for several scatterer sites and excitation source types.
