The first part of this work considers the problem of radiation from sources in the presence of smooth, convex, impenetrable objects and presents a brief survey of various high-frequency techniques. A generalization of the geometrical theory of diffraction and two new techniques -- based on the spectral domain approach and an asymptotic evaluation of the radiation integral for the surface current -- also are discussed. Some numerical results derived from the spectral domain formulas are presented, and a comparison with available theoretical and experimental data is included. The second part of this work describes a new technique for analyzing the radiation from a point electromagnetic source located on an infinitely conducting solid cylinder with a finite length. The method presented in this work is based upon a generalization of STD to the case of curved surfaces.
