Title: Theory of propagation of low frequency terrestrial radio waves
Description: The various forms of the solution of Maxwell's equations for the propagation of low frequencies in the waveguide between a spherical earth and a concentric ionosphere are given in concise form. A tutorial discussion is given of the various solutions to acquaint experimenters with the practical techniques which are available.
