Subsurface Electromagnetic Response of a Conducting Sphere Embedded in a Two-Layer Conductor

Abstract

D'YAXONOV'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.
