On Taylor-series approximation of the response of electromagnetic field on a two layered earth model with a conductive overburden

Abstract

We investigate the structure of a two layered earth by presenting a mathematical model of electromagnetic response. The integral expressions provide the electric fields on the ground surface, and Taylor-series expansion are used to find the solution of the electric field. Numerical solutions are computed and plotted to show the behaviors of the electric field while some parameters are assigned approximately. The responses of electric field from the ground surface are influenced by the conductivity of overburden. © 2013 Academic Publications, Ltd.
