The GTD relies upon the known asymptotic solutions of canonical problems and these solutions play a two-fold role — they help validate the enu

Spectral Theory of Diffraction, encountered with the GTD. The basic strategy followed in STD is to represent a complex field, which is not a ray field, in terms of a superposition of plane waves. Such fields are often encountered in diffraction problems.

In particular, difficulties arise on the cusp lines of the caustic surface where the formulas of Sect. 5.7 no longer apply. A particular

We saw in Chap. 1 that, in a majority of cases, this approach not only provides useful tools for calculating the fields diffracted by an object, but also helps us to physically interpret the results in terms of rays.

In this chapter, we begin by enunciating the principles of ray optics and show how they enable us to extract the essential characteristics of various scattering phenomena.
