Abstract

The volume integral technique solves the electromagnetic diffusion equation for the electric field vector E in the presence of a flaw of conductivity σh in a host medium of conductivity Given the electric field, the impedance change in a probe coil may be computed. The technique has been used to model electromagnetic data collected in geophysical exploration programs [1].
