Abstract :
The ultimate goal of this work is to obtain accuracy for the MFIE that is just as good as the EFIE for Rao-Wilton-Glisson (RWG) basis functions. It is hoped that regularization will provide similar benefits for RWG as for pulse functions, since RWG basis functions have a pulse type dependence (abrupt edge) on two sides of each triangular mesh element.
