A technique to combine the geometrical theory of diffraction and the moment method
Abstract
The geometrical theory of diffraction is conventionally applied to scattering and antenna problems in which the structure is large in terms of the wavelength. Diffraction solutions, however, exist for relatively few geometries. On the other hand, the method of moments can be applied to arbitrarily shaped objects, provided the overall size is small compared to the wavelength. A method is proposed which by combining the two approaches makes it possible to handle numerous problems which could not be solved otherwise.
