Transient Analysis of Plane Wave Reflection from a Lorentz Half Space

Abstract

A time domain technique based on numerical inversion of Laplace transform is extended and applied to transient analysis of pulses reflected from a Lorentz half space both for TE and TM cases. Its correctness and effectiveness are validated by comparing our results with those published in the literature. With this technique, the TM case when the incident angle is equal to 450 does not need to be processed separately and can be treated as a general case for any incident angle. This technique brings good accuracy in both late and early time, a simple algorithm, short calculation time, small required memory size and readily controlled error.
