Subsurface electromagnetic response of a conducting sphere embedded in a two-layer conductor.

Abstract

D'YAKONOV'S (1959) method for a sphere embedded in a uniform conducting half space for an overhead vertical magnetic dipole has been extended to the case of a sphere embedded in the lower layer of a two layer conducting half space. The fields are evaluated at the interface of the two layer conductor.The numerical results obtained for a range of geophysical parameters have possible applications in the interpretation of ocean floor electric and magnetic field measurements.
