Paper Abstract

This paper shows how Soramerfeld's multiple-valued function method can be extended to solve Fresnel three-dimensional diffraction problems for a point radiation source and perfect conductors in two different configurations: a semi-infinite plane and a circular disc. Characteristically, the solutions are in closed form, can be directly calculated and are without any restriction on the relative sizes of radiation wavelength and scatterer.
