Diffraction of the creeping waves generated on a perfectly conducting spherical scatterer by a ring source
Abstract
The analysis of diffraction results in explicit expressions for certain coefficients related to the diffractions occurring at the edges of spherically curved reflectors. The analysis is made using a recently developed integral transform technique. Various ray contributions are isolated, and fairly simple nonuniform expressions for the diffraction coefficients are derived. In addition, the surface diffraction coefficient and the attenuation constant are obtained as well. The results are in complete agreement with those obtained by Keller (1953, 1956).
