About this ebook
An approximate theory for conversion of modes in an earth-ionosphere waveguide is propounded.The model is two concentric spherical reflecting boundaries which have prescribed surface impedances.The localized irregularity at either the ground or the ionosphere is idealized by a 'black screen' which effectively blocks the cross-section of the waveguide over a portion of its area.In this sense, the method is a union of approximate Kirchoff diffraction theory and rigorous mode theory.(Author).
