Theoretical Study on the Correlation between Wideband Electromagnetic Spectra and Geological Structures.

Abstract

A theoretical study has been performed to establish a mathematical means to compute the electromagnetic response of an earth having continuous and arbitrary conductivity variations, and to formulate a transfer function that can convert a wideband frequency-domain response to a continuous conductivity-depth function. The study was based upon past experiences in both theoretical and experimental aspects of frequency-domain electromagnetic method. A new formal integral representation was formulated for Maxwell's equations for a medium having an arbitrary conductivity function. It was shown that the representation is suitable for forward problems and, through a proper integral transform, the inverse may possibly exist. An attempt is being made to derive a transfer conductivity-depth profile. (Author)
