Asymptotic Analysis of a Line Source Diffraction by a Perfectly Conducting Half-plane in a Bi-isotropic Medium
This paper is concerned with the diffraction of an electromagnetic wave by a perfectly conducting half-plane in a homogeneous bi-isotropic medium (asymptotically). Similar analysis in a source-free field is done in S. Asghar and A. Lakhtakia (1994), Planewave diffraction by a perfectly conducting half-plane in a homogeneous bi-isotropic medium. Int. J. Appl. Electromagnetics in materials, 5, (1...
متن کاملDiffraction of a Dipole Field by a Perfectly Conducting Half Plane
The problem of the diffraction of a dipole field by a perfectly conducting half plane or wedge has attracted considerable attention and the literature dates back over half a century. One of the earliest investigations was that of Bromwich (1915) who sought to deduce the solution from a Hertz vector made up of the known solution for the corresponding scalar problem, but it was later realized tha...

Diffraction of a plane inhomogeneous electromagnetic wave by a perfectly conducting half-plane in an absorbing medium
The Sommerfeld’s problem of plane wave diffraction by a perfectly conducting half-plane is considered for the general case of an absorbing medium and an inhomogeneous incident wave, whose the constant phase planes are not parallel to the constant amplitude ones. The exact solution is represented in terms of parameters of incident wave propagation in the coordinate axes, but not in terms of angu...
متن کاملThe Uniform geometrical Theory of Diffraction for elastodynamics: Plane wave scattering from a half-plane.
Diffraction phenomena studied in electromagnetism, acoustics, and elastodynamics are often modeled using integrals, such as the well-known Sommerfeld integral. The far field asymptotic evaluation of such integrals obtained using the method of steepest descent leads to the classical Geometrical Theory of Diffraction (GTD). It is well known that the method of steepest descent is inapplicable when...
