Efficient approach for full-wave modelling of grounding systems is provided. First the electric field integral equations are cast in form that is more suitable for grounding analysis and have improved convergence. Then numerical evaluation of the Sommerfeld integrals is substituted by bivariate cubic interpolation procedure of the solutions from pre-computed interpolation grid. This procedure provides...
Electromagnetic Models (EM) for analysis of grounding systems are based on least possible approximations in the solution of Maxwell's equations. The complexity of the EM calculations motivated the creation of more engineer-oriented and less time consuming methods for analysis of grounding systems. One of the most commonly used methods is the transmission line (TL) model. In this paper a new, improved...
