Introduction to the Uniform Geometrical Theory of Diffraction (Artech House Microwave Library)

Knowledge of the geometrical theory of diffraction ( GTD) is best accomplished in two steps. On first looking into the subject we should accept the principal results and concepts, properly understand their various parameters, and apply the methods to a wide variety of problems-this, roughly, is the way we first approach network theory. Once this has been accomplished, the asymptotic methods used to piece together the GTD coefficients can be studied through the many scholarly works available in engineering and mathematical journals. This text has been written to provide a means of achieving the first step. A text for senior undergraduate or beginning graduate students, as well as practicing engineers, that bridges the gap between specialist papers and the use of GTD in practical problems. It introduces the principal results and concepts, their various parameters, and applications to a wide variety of
