Transient analysis of plane wave reflection from a Debye half space

Abstract

In this paper, an efficient time domain technique is developed to solve the impulse response of a Debye half space without performing tedious and complicated mathematical manipulations. Both horizontally and vertically polarized plane waves that are obliquely incident onto the interface between free space and a Debye medium are discussed. This technique is based on numerical inversion of Laplace transform, leads to good accuracy, and has a simple algorithm, short calculation time, small required memory size, readily controlled error and wide application range. The achieved results are meaningful and useful in microelectronics, phonics, material science and biomedical engineering, and agree very well with those published in the literature, validating the correctness and effectiveness of our technique.
