Approximate Expressions for the Magnetic Field from an Electric Current Source in a Layered Conducting Medium

Abstract

An electric current source comprising point horizontal electric dipoles is proposed. An approximate description of the magnetic field from such a source is given. The Environments considered are two-layer (2 semi-infinite media, typically the air and the sea) and three-layer (2 semi-infinite layers separated by a conducting slab, typically the air, sea and sea-bed)
