ELF Scattering in the Earth-Ionosphere Waveguide

Abstract

Slab-model implementation of ELF scattering by a cylindrically symmetric but radially varying ionospheric disturbance is explored. The ground- based transmitter and receiver may be located beneath the disturbance or outside its projection on the ground. Amplitudes and phases of the laterally dependent part of all transverse magnetic (TM) field components are calculated as a function of range for a given location of the disturbance or as a function of disturbance location for a fixed range. Although partial sum convergence difficulties limit its general utility, the resulting program can be used for a variety of case studies. Examples given include drifting sporadic-E patches, a nuclear depression, and a weak solar proton event.
