Method of Line for Modeling of Grounding Electrodes Buried in Stratified Multilayer Soil

An efficient full-wave semi-analytical method based on the method of line is developed for rigorous modeling of grounding electrodes buried in stratified multilayer soil. As compared to the existing full-wave modeling techniques, the proposed method is extremely computationally efficient while enables modeling of any number of vertical and/or horizontal soil layers. Furthermore, the proposed method is not prone to any stability or convergence numerical issue. The efficiency and accuracy of the proposed method is evaluated using the cases of horizontal and vertical grounding electrodes buried in vertically or horizontally stratified multilayer soil.
