Mathematical Modelling of Electromagnetic Response on a Multilayered Earth with a Layer Having Exponentially Varying Conductivity

Abstract:The goal of this paper is to present a mathematical modelling of elec-tromagnetic response of a multilayered earth with a layer having exponentially varying conductivity. The general case can be broadly divided into four cases. By solving the model, integral expressions give the electric field on the surface of a multilayered earth. Numerical experiments on computer simulation indicate that the anomalous responses of the real and imaginary parts of the normalized electric field at the earth’s surface are dominated by the layer having exponentially varying conductivity profile
