A Method for Efficient Computation of Time Domain Surface Impedances of A Lossy Half Space

In this paper, an efficient technique is developed to solve the inverse transform of exact closed form representations of frequency domain surface impedances, without pursuing tedious and complicated mathematical manipulations. This technique is based on the numerical inversion of the Laplace transform and has the advantages of simple programming, computational efficiency and easy error control. The numerical results agree very well with those published in the literature, validating the effectiveness of this technique.
