Abstract:

A computer program for calculating ELF propagation in a laterally nonuniform earth ionosphere waveguide is presented. The program is based on a simple surface propagation model formulated in terms of an integral equation which is solved using a moment method. The disturbance must be localized to the extent that the waveguide disturbance must effectively vanish outside a rectangle of several megameters on a side. The program allows for modeling rectangular, circular, and elliptical disturbances. The lateral propagation function for the vertical electric dipole is calculated. Waveguide height effects are allowed for within the spirit of the WKB approximation. The total vertical electric field is also calculated. Author
