An E-polarized electromagnetic plane wave is obliquely incident on three parallel metal half-planes which are perpendicularly truncated by a metal plane. The scattered field is determined to satisfy an integral equation, which is solved numerically.
The aim of this paper is to apply the Generalized Wiener Hopf (GWH) technique to obtain the solution of the scattering by a three part PEC plane. In developing this task we observe that a novel network representation in the Laplace domain of a semi layer slab bounded by a PEC is required. This representation of semi layer slab is based on the Fredholm factorization. The circuital representation of...
The aim of this paper is to apply the Generalized Wiener Hopf technique (GWHT) to obtain the solution of the scattering by impenetrable wedges bounded by angular sectored media with different electromagnetic parameters. According to the general theory developed in earlier papers we always are able to reduce the problem to a Fredholm integral equations (FIE) of second kind amenable of very accurate...
This paper describes a novel methodology to model via networks scattering problems constituted of angular regions. The technique is based on the Generalized Wiener-Hopf Technique and it is able to study novel scattering problems constituted of angular regions and layered regions.
The aim of this paper is to resort to the Generalized Wiener Hopf (GWH) technique to obtain the solution of a new canonical problem constituted by a planar waveguide flanged by a PMC wall. While developing this task we observed that the network representation in the Laplace domain of an angular region bounded by a PCM wall is required. This representation is constituted of a problem of Fredholm factorization...
A circular cylindrical metallic resonator with four alternating sectors of DPS and DNG materials is analyzed, in the frequency domain. The two materials are linear, lossless, homogeneous, and anti-isorefractive to each other. The electric field is assumed to be parallel to the cylinder axis. It is also shown that the resonator's dispersion relation is always satisfied for particular geometries. Numerical...
A perfect electric conductor wedge lying on a dielectric half-space is analyzed, in the frequency domain. The structure is excited by a plane wave coming from the free space region. The problem is formulated using generalized Wiener-Hopf equations and an approximated solution in terms of spectral quantities is proposed by discretization of Fredholm integral equations. Numerical results for several...
A metallic cylindrical resonator partially filled with double-negative (DNG) metamaterial with sector shape is analyzed in the frequency domain. The remaining part of the resonator is filled by a doublepositive (DPS) medium. The structure results in a cylindrical resonator of finite length with a metamaterial wedge whose edge is on the cylinder axis. A line source excitation located in the DPS region...
