Application of Analytical Expressions for Retarded-Time Potentials in Analyzing the Transient Scattering by Dielectric Objects

Application of analytical formulas for the retarded-time potentials in Müller- and PMCHWT-type time-domain integral equations (TDIEs) is presented. The impulsively excited scalar and vector potentials are evaluated in closed form, and the coupling coefficients can be calculated with high accuracy. Examples of transient analysis of the electromagnetic… (More)
