A Hybrid Method for the Solution of Plane Wave Diffraction by an Impedance Loaded Parallel Plate Waveguide

Abstract

Abstract-The diffraction of E-polarized plane waves by an impedance loaded parallel plate waveguide formed by a two-part impedance plane and a parallel half plane with different face impedances is investigated rigorously by using the Fourier transform technique in conjunction with the Mode Matching Method. This mixed method of formulation gives rise to a scalar Modified WienerHopf equation, the solution of which contains infinitely many constants satisfying an infinite system of linear algebraic equations. A numerical solution of this system is obtained for various values of the surface impedances and waveguide height.

Research on Three Types of Rhombus Lattice Photonic Band Structures

“…PBG of a rhombus lattice PC for TM and TE modes can be achieved using plane wave expansion method [14][15][16]. In our calculation, 441 (10 ≤ h 1 , h 2 ≤ 10) reciprocal vectors per unit cell are used and the convergence is better than 2%.…”

Diffraction of Em Plane Wave by a Slit in an Impedance Plane Using Maliuzhinets Function

“…Moreover, the application of geometrical theory of diffraction (GTD) to the scattering from a wedge with impedance faces is applicable to the analysis of practical structures involving edges in an impedance surface. It may be noted that scattering from slits, half plane, impedance surfaces and study of high frequency diffraction are topics of current interest [2][3][4][5][6][7][8][9][10][11][12][13].…”

A Note on Spherical Electromagnetic Wave Diffraction by a Perfectly Conducting Strip in a Homogeneous Bi-Isotropic Medium

“…In recent years, propagation of plane waves with negative phase velocity and its related applications in isotropic chiral materials can be found in [23][24][25][26]. It may be noted that scattering from strips, slits, half plane, impedance surfaces and study of high frequency diffraction are topics of current interest [37][38][39][40][41][42][43][44][45][46][47][48].…”
