Abstract

The quasistatic fields generated by an electrode mounted on a perfectly conducting pad of finite extent and embedded in a planar stratified medium are analyzed. An integral equation in the spectral domain is derived for the outflowing current density distribution on the pad-electrode surface. The method of moments is then applied to solve the integral equation. The effects of the electric properties of the stratified medium and the standoff thickness on the total electrode current are investigated. Several conductivity profiles modeling different practical measurement environments are also considered
