Analysis of Electromagnetic Scattering from Dielectric Applying M uller Integral Equation

In th is paper, we present a set of num erical schem es to solve the M u lle r integral equation for the analysis of electrom agnetic scattering from arbitrarily shaped three-dim ensional dielectric bodies by applying the m ethod of m om ents (M o M ). T he piecew ise hom ogeneous dielectric structure is approxim ated by planar trian g ular patches. A set o f the i?W G (R ao , W ilto n, G lisson) functions is used for expansion o f the equivalent electric and m agnetic current densities and a com om ation of the R W u function and its orthogonal com ponent is used for testing. N um erical results for a dielectric sphere are presented and com pared w ith solutions obtained using other form ulations.
