Comments on “New Methodology for Representing Soil Ionization in FDTD Simulations of Grounding Electrodes”
This article comments on a recent IEEE Trans. EMC paper titled “New methodology for representing soil ionization in FDTD simulations of grounding electrodes,” where the Liew–Darveniza algorithm (1974) is used. We show that the assumption of cylinder-hemisphere equipotential patterns is not physically sound and propose an alternative that uses confocal hemi-ellipsoidal equipotential patterns.
