Abstract

This paper presents a model order reduction algorithm for the surface electric field integral equation (EFIE) formulation of the electromagnetic wave scattering problem. The method allows fast and accurate frequency sweep calculations of electromagnetic wave scattering from a perfectly conducting (PEC) three-dimensional object. We apply the well-conditioned asymptotic waveform evaluation (WCAWE) method to circumvent the computational complexity associated with the numerical solution of such formulations. Practical implementation issues are addressed with numerical examples given to illustrate the accuracy and robustness of the proposed methods.
