Far-field analysis of the Malyuzhinets solution for plane and surface waves diffraction by an impedance wedge
Andrew N. Norris,Andrey Osipov +1 more
TL;DR: In this paper, the authors considered the problem of determining the far-field scattered from the edge of a wedge of exterior angle 2 with arbitrary impedance conditions on either face, and provided a simple solution in the form of a Sommerfeld integral obtained by Malyuzhinets.

On the investigation of diffracted fields at the shadow boundaries of staggered parallel plates—A spectral domain approach
Yahya Rahmat-Samii,Raj Mittra +1 more
TL;DR: In this paper, the diffraction of plane waves by two staggered parallel plates is investigated using the spectral diffraction coefficient in the Fourier transform domain, and the total field can be represented in terms of a double Fourier integral, a result that is identical to the one derived by Jones via the Wiener-Hopf technique.
Journal ArticleDOI
On the role of the geometrical optics field in aperture diffraction
R. Menendez,S. Lee +1 more
TL;DR: In this article, the authors studied the asymptotic solution of a high-frequency electromagnetic field transmitted through a finite aperture and deduced simple and explicit rules for the role of the geometrical optics field and the regions of validity for GTD in a general aperture diffraction.
Journal ArticleDOI
Caustics and caustic corrections to the field diffracted by a curved edge
TL;DR: In this paper, the caustics for the singly diffracted rays from a circular disk are investigated when the rays emanate from a source which is placed off the axis of the disk.
Journal ArticleDOI
Ray-optical analysis of reflection in an open-ended parallel-plane waveguide: II-TE case
TL;DR: In this paper, a ray-optical solution for a TE mode traveling toward the end of a semi-infinite parellel-plane waveguide is solved by ray methods.

Uniform asymptotic theory of edge diffraction
Robert M. Lewis,J Joop Boersma +1 more
TL;DR: In this paper, a uniform asymptotic theory of diffraction was proposed, which is uniformly valid near edges and shadow boundaries, but not at any caustics other than the edge.
Journal ArticleDOI
Diffraction of a Scalar Wave by a Plane Screen
TL;DR: In this paper, a method for obtaining a uniform representation of the diffracted field produced when a scalar wave is incident upon a plane screen with a curved edge is presented, where the first term in this representation is continuous at the edge and on the shadow boundaries.
