Characterization of a transient wave reflected from a lossy half space using numerical inversion of laplace transform

摘要

In this article, one method based on numerical inversion of Laplace transform is applied to the transient analysis of the reflected wave from a conducting interface for both vertical and horizontal incidence. This method is applicable to any relative dielectric constant and incident angle, leads to good accuracy in both late and early time, and has a simple algorithm, short calculation time, small required memory size, readily controlled error and wide application range. Comparison between our results and the published results confirms the correctness and effectiveness of this approach.
