A WKB Program for ELF/VLF Earth-Ionosphere Excitation by Sources at Satellite Heights.

Abstract

This report presents a variation of an earlier program for calculating ELF/VLF excitation of the earth-ionosphere waveguide by point dipoles at satellite heights. The variation consists of implementing WKB formalism developed for the purpose of speeding up the requisite field integrations. Allowance is made for the following: (1) calculating excitation factors for all electric field components E sub x, E sub y, and E sub z; (2) calculating excitation by both electric and magnetic point dipoles; (3) calculating excitation by vertical, horizontal end-on and horizontal broadside configurations. A mode sum computer program is also included as an illustration of how the excitation factors are used in field calculations. (Author)
