Mode Conversion Program for an Inhomogeneous Anisotropic Ionosphere.
Abstract
The report presents a program for numerically determining mode conversion coefficients and mode sums for a waveguide which is inhomogeneous along the direction of propagation. The program allows for vertical inhomogeneity of the ionosphere as well as its anisotropy due to the geomagnetic field. The model assumes the perturbation has no horizontal space dependence perpendicular to the transmitter receiver line. Mode conversion coefficients are obtained by ignoring reflections associated with the inhomogeneity along the direction of propagation. The latter assumption greatly simplifies the calculations and appears to be justified for a broad class of horizontal inhomogeneities. However, its validity under severe artificial ionospheric disturbances requires further study. (Author)
