S. Terranova, G. Manara, L. Klinkenbusch: "A Physical Insight into Complex-Source Beam Diffraction by a Wedge", 2nd URSI AT-RASC, Gran Canaria, 28 May – 1 June 2018

Written by

An extension of the Uniform Geometrical Theory of Diffraction (UTD) has been recently proposed to analyze Complex-Source Beam (CSB) diffraction by a perfectly electrically conducting (PEC) wedge. In the context of high-frequency techniques, the proposed simple and compact solution has been written in terms of incident,
reflected and diffracted contributions, so that it can be directly applied to calculate the scattering from more complex geometries with edges. The purpose of this paper is to show the accuracy of the above approach through comparisons with a rigorous solution obtained by a multipole expansion of the scattered field. A physical
insight into the involved phenomena is also gained.
