Excerpt from Diffraction in Inhomogeneous Media
This theory differs from ordinary geometrical optics by the inclusion of certain additional rays called diffracted rays and others called complex or imaginary rays. The former are associated with the boundaries or discontinuities of the medium while the latter are associated with refraction shadows which occur in the absence of boundaries. In addition to characterizing these new rays, the theory also provides a method for calculating the field associated with them.

Paperback. Zustand: New. Print on Demand. This book outlines a new theory in diffraction, extending geometrical optics to fully describe diffracted fields. This extension, called the geometrical theory of diffraction, incorporates certain additional rays called diffracted rays and complex or imaginary rays into the analysis of wave propagation in inhomogeneous media. The diffracted rays are associated with boundaries or discontinuities of the medium, while the latter are associated with refraction shadows that occur in the absence of boundaries. Not only does this theory characterize the new rays, it also provides a method for calculating the field associated with them. The author explains this method and applies it to a number of problems, also demonstrating how the new theory agrees with exact solutions of boundary value problems for partial differential equations. This book will be of interest to anyone involved in the study of wave diffraction. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Bestandsnummer des Verkäufers 9781332120758_0
