A FORTRAN PROGRAM FOR MODE CONSTANTS IN AN EARTH-IONOSPHERE WAVEGUIDE

Abstract

An updated version of an earlier waveguide program has been written in the FORTRAN compiler language. The new program includes the following alterations or additions: (1) An improved Runge-Kutta routine; (2) A procedure which finds directly the starting solutions at the top of the ionosphere; (3) Provision for including up to five charged particles; (4) A method for economically finding approximate waveguide solutions; and modifications for use of the program for ELF wave propagations.
