Propagation of vertically and horizontally polarized waves excited by distributions of electric and magnetic sources in irregular stratified spheroidal structures of finite conductivity – generalized field transforms

Abstract

Transform pairs for the electromagnetic fields in radially stratified spherical structures are derived. These field transforms are used to convert Maxwell's equations into generalized telegraphists' equations for the scalar wave amplitudes. Arbitrary distributions of electric and magnetic sources are considered and the full-wave expansions account for both vertically and horizontally polarized waves. The analysis in this paper also provides the basis for the complete expansion of the electromagnetic fields in irregular spheroidal structures (bodies of revolution) in which the medium is varying as a function of the radial distance and the latitude. This work can be applied to propagation in irregular ionospheric and tropospheric ducts.
