Pulsed Electromagnetic Diffraction by a Semi-Infinite Sheet With Conductive and Dielectric Properties

The 2-D diffraction of a pulsed electromagnetic (EM) plane wave by a semi-infinite sheet with conductive and dielectric properties is analyzed analytically with the aid of the Wiener–Hopf technique and the Cagniard–DeHoop technique. Novel exact analytical expressions describing the time-domain (TD) EM field in the presence of the conductive half-plane are derived. Moreover, closed-form approximate TD expressions are arrived at via Koiter’s approximate method of factorization. Illustrative numerical examples are presented.
