A Wavelet-Collocation Approach for Computational Electromagnetics

Abstract

A wavelet-collocation scheme, constructed from the discrete singular convolution (DSC) is introduced for computational electromagnetics. The basic philosophy behind the DSC algorithm is studied. Four test problems, including waveguide analysis in both regular and irregular domains, electromagnetic wave scattering, electrostatic field estimation via potential functions, and electromagnetic wave propagation in three spatial dimensions, are employed to illustrate the usefulness, test the accuracy and explore the limitation of the wavelet algorithm. Computational accuracy of the wavelet algorithm is shown to be controllable and is compared with a standard approach. Numerical experiments indicate that the proposed wavelet algorithm is a promising approach for solving problems in electromagnetics.
