Excerpt from Decay Exponents and Diffraction Coefficients for Surface Waves on Surfaces of Non-Constant Curvature
When a wave is incident upon an opaque object large compared to the incident wavelength a shadow is formed. Some radiation penetrates into the shadow. The first quantitative analysis of this penetration effect for the case of a smooth object was that of G. N. Watson[1]. He showed that the field in the shadow of a sphere consists of a sum of modes.

Paperback. Condizione: New. Print on Demand. This book, examining the theory of diffraction, describes radiation traveling along surface rays, their geodesics originating at the shadow boundary, continuously emitting diffracted rays that irradiate the shadow and enter the illuminated region. The author extends geometrical theory to longer wavelengths than could be treated with previous understanding. The theory has been tested by comparing its predictions with the exact solutions of diffraction problems involving objects of non-constant curvature. Extending the theory to encompass these objects, the author achieves predictions that coincide with the geometrical theory. Presenting diffraction theory in novel ways, the author provides results and concepts that will facilitate further research on radiation traveling along surface rays.
