Electromagnetic scattering analysis using the two-dimensional MRFD formulation

Recently developed multiresolution frequency domain (MRFD) technique is applied to two-dimensional electromagnetic scattering problems. Scattered field formulation and perfectly matched layer is implemented into the MRFD formulation. Far field distributions of dielectric and perfectly electric conductor (PEC) bodies are calculated and bistatic echo widths of these structures are presented. Good agreement between MRFD and FDFD results is recognized. It is observed that the MRFD technique demonstrates superior computational efficiency characteristics compared to the traditional FDFD technique.
