Excerpt from Made Conversion in the Earth-Ionosphere Waveguide
The method is based on a union of approximate Kirchoff diffraction theory and rigorous mode theory. To simplify the discussion, the problem is considered to be two-dimensional in nature and, thus.

Paperback. Condición: New. Print on Demand. This book proposes an approximate theory for conversion of modes in an earth-ionosphere waveguide. The model is two concentric spherical reflecting boundaries with prescribed surface impedances. It's applicable to irregularities at either the ionospheric reflecting layer as well as at the earth's surface, like a mountain ridge transverse to the propagation path. The method is based on a union of approximate 'Kirchoff diffraction theory and rigorous mode theory. An example in the latter category would be a mountain ridge which is transverse to the propagation path. The author posits that localized irregularities can be idealized by a 'black screen' which effectively blocks the cross-section of the waveguide over a portion of its area. This book presents important formulas for calculating modal coefficients to predict the behaviour of electromagnetic waves in such scenarios.
