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.
