Overhead and buried conductor system

Computing the electromagnetic field of the system of arbitrarily positioned conductors in horizontally stratified multilayer medium

“…On the other hand, high-frequency EM field phenomena, for example, often associated with dissipation of lightning surge currents through grounding grids, are also of significant interest. This problem of numerically computing time-harmonic EM fields and associated potential distributions due to the system of energized conductors, have already been treated by a number of authors, for example, [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. In these papers, applied methodologies range from the method of moments, finite element method, boundary element method, finite-difference time-domain method, to name a few.…”

“…The majority of the developed numerical codes account for the two-layer medium, that is, air and homogenous soil, for example, [2][3][4][5][6][7][8][9][10]. Some of them are able to account for the horizontally stratified multilayer medium, for example, [11][12][13][16][17][18], whereas fully heterogenous medium is scarcely been accounted for, with only a handful of noteworthy exemptions to this rule; for example, see [20] for more information.…”
