The Journal of Korea Navigation Institute, 2015 In this paper, the electric potential of electrode surface is investigated by assuming them as two dimensional sets of point current sources. And, the simulated water tank is manufactured as a reduced scale of the earth. Henceforth, the adequate model electrode for test is decided to decrease experimental errors relevant to the limitation of the size ...

Grid-Ground Electrode in Two Layered Non-Homogeneous Ground
7th Symposium on Applied Electromagnetics SAEM`18: Conference Proceedings, 2019 In this paper, a procedure including using of the Green’s functions for a point source in multilayered media for the electric scalar potential and the Method of Moments-MoM for analyzing described problem is adopted. The approach provides generating Green’s function of the point source for arbitrary number of homogeneous layers. Also, it is possible to
