Abstract

The wideband electromagnetic wave scattering from arbitrarily shaped, three-dimensional (3D) dielectric objects is investigated using the Method of Moments (MoM) in conjunction with the Asymptotic Waveform Evaluation (AWE), Generalized Minimal Residual method (GMRES) and Fast Fourier Transform (FFT). Numerical results are presented which demonstrate the accuracy and computational efficiency of the technique in comparison with analytical and conventional numerical methods.
