A FINITE-DIFFERENCE STUDY OF THE EFFECT OF CURRENT AND CHARGE SOURCES ON THE ELECTROMAGNETIC FIELD OF THE EARTH

Abstract

A finite-difference approach to the description of the electromagnetic field structure within the region bounded by the earth and some outer spherical boundary is studied. Within this medium, a current sheet and a free charge sheet are assumed to exist in a spherical geometry. The medium is assumed to be two-dimensionally inhomogeneous and to consist of a plasma gas. The earth is considered to be perfectly conducting, and the field distribution at the outer boundary is caused to assume the form of a system of spherical waves which are propagating outwardly.
