The theory of propagation of short radiowaves in a spherically stratified atmosphere

The initial conditions of the boundary value problem of radiowave propagation in a spherically stratified atmosphere are reformulated using the submersin method. The initial boundary value problem is divided into four individual cases, with both the source and the receiver on the surface of earth; the source on earth and the receiver within the atmospheric layer; the source within the layer and receiver on the ground; and both the source and the receiver within the layer. These are solvedon using a closed-form differential equation and quadrature. The equations are noted to be convenient for the analysis of waveguide propagation of radiowaves above the sea surface.
