Numerical Results for VLF Mode Conversion in the Earth-Ionosphere Waveguide

Abstract

Numerical results are presented for several mode conversion models which allow for the inhomogeneity and anisotropy of the ionosphere. It is concluded that reflections associated with propagation across the terminator do not significantly affect mode conversion. It is shown that significant departure between mode conversion and WKB mode sums can occur when propagating across the terminator even for transition thicknesses as great as 1000 km. Numerical results are compared with the experimental modeling results of the American Nucleonics Corporation.
