Radio waves in an irregular spheroidal model of the earth-ionosphere waveguide

Describes a program to compute the amplitude and phase anomalies of the electromagnetic fields in a perturbed spheroidal model of the Earth-ionosphere waveguide characterized by an effective height that varies along the propagation path, and also to trace the loci of the mode numbers in the irregular region of the spheroidal waveguide and to compute the transmission and reflection scattering coefficients. The language used is Fortran IV
