Simplified VLF/LF mode conversion program with allowance for elevated, arbitrarily oriented electric dipole antennas
Abstract
This report presents an updated version of an earlier simplified mode conversion program for VLF/LF propagation in the earth-ionosphere waveguide. The new program includes the provision for calculating at an arbitrary height. Within the guide, all three electric field components were generated by an electric dipole of arbitrary orientation and height. The program is designed for treating air to air, ground to air, or air to ground VLF/LF problems involving a waveguide channel which is horizontally inhomogeneous along the direction of propagation.
