Wave propagation in an anisotropic three-layer model
Abstract
The present paper is concerned with the propagation of VLF-waves between earth and ionosphere; the ionosphere is regarded as rendered electrically anisotropic by a static uniform vertical magnetic field. With help of the reflection-matrix method field distributions of a vertical electrical dipole are calculated and exact solutions are obtained in form of integral representations. Their integration leads to mode series and integrals along the branch cuts. The contributions of these branch cuts are found to be negligible for large distances. The analytic expressions are evaluated numerically for various physical and geometrical parameters and the influence of the anisotropy is studied.
