Some large-scale scattering and near-field results computed by the hybrid finite element - boundary integral - multilevel fast multipole method

The primary aim of this paper is to present a series of large-scale scattering results obtained by the hybrid finite element-boundary integral (FEBI) technique, where high-resolution range (HRR) profiles are generated from broadband frequency domain data and nearfield results are computed from the BI currents by a multilevel fast multipole method (MLFMM) accelerated postprocessing algorithm
