A Novel Time-Domain Reflection Coefficient Function: TM Case
In determining electromagnetic transient response of structure placed above the half space, the half space properties can be taken into account via the reflection coefficient (RC) approximation. The choice of an RC function used in RC approximation is often important with regards to accuracy and computational efficiency of the overall method. In this paper, a new time-domain RC function for the case of TM polarization is presented. The function is derived using Gaver-Stehfest algorithm for numerical inverse Laplace transform and does not require the use of Bessel functions. The resulting formulation is rather simple, and, as the results indicate, accurate and computationally efficient.
