A STUDY OF THE TRANSMISSION OF PLANE HYDROMAGNETIC WAVES THROUGH THE UPPER ATMOSPHERE,

Abstract

A new conductivity dyadic was used to study the propagation of ordinary and extraordinary modes of wave propagation in a partially-ionized gas. The conductivity tensor included effects of all collisions and the motion of neutral particles. Medium parameters were those of the earth's upper atmosphere. The range of frequencies considered was that of geomagnetic micro-pulsations, 0.00110.0 cps. Geomagnetic equatorial regions received special attention. Incoming incident waves were assumed on a plane-stratified ionosphere. Resultant steady-state frequency responses, impulse responses, current density, electric field, and power dissipation profiles, and power spectra for daytime and nighttime atmospheres were computed. A study of coupling between the two characteristic modes showed appreciable collisional coupling in the lowest ionosphere. (Author)
