Expresiones aproximadas de voltajes originados por fuentes puntuales de corriente en suelos biestratificados

Abstract

Common expressions for potential and resistance of linear electrodes in bi-stratified soils involve calculations with infinite series. The speed of convergence of these series depends on the K reflection factor associated with the resistivities of the surface and lower layer of the soil. Infinite series emerge as a consequence of the inversion from the spectral domain where algebraic solution of the problem is found. The proposed exponential approximation allows direct inversion from the spectral domain avoiding infinite series.
