Observation of Proximity Resonances in a Parallel-Plate Waveguide
Experiments with dielectric scatterers in a parallel-plate waveguide have verified for the first time the existence of proximity resonances in two dimensions. A numerical solution to the scattering problem supports the analysis of the experimental data. It has recently been shown that two resonant s-wave scatterers placed close together produce two resonances in the spectrum of the combined sys...
متن کاملDiscrete and Continuous E-Plane Bends in Parallel-Plate Waveguide
Discrete bends in the propagation direction of plane TEM waves can be achieved utilizing the Brewster angle at a planar interface between media of different uniform isotropic pennittivities. This paper extenda this to cases of multiple dielectric or nonuniform permittivity. The nonuniform case is a generali~tion of the Brewster-angle concept. This is also related to special log-spiral solutions...
متن کاملMultifaceted terahertz applications of parallel-plate waveguide: TE1 mode
Presented is a review of recent work by the authors in which the lowestorder transverse-electric (TE1) mode of a parallel-plate waveguide (PPWG) is used for terahertz (THz) applications. This work adds a new dimension to the multitude of diverse THz applications made possible by PPWGs. Using the TE1 mode, demonstration is presented of an ultra-low loss THz waveguide, a highly sensitive microflu...
متن کاملIty of Modes in a Parallel Plate, Anisotropic Waveguide Using a Modified, Coordinate Transformation
The excitation of forward and backward, Electromagnetic (EM) modes and fields in an anisotropic, parallel plate waveguide (meeting Dirichlet and Neumann boundary conditions), is studied, using a modified coordinate transformation which reduces Maxwell’s equations to the form of a Helmholtz wave equation satisfying Dirichlet and mixed-partial derivative boundary conditions. The EM modes and fiel...
متن کاملEquivalent Susceptance of a Circular Iris in a Parallel Plate Waveguide
An approximate formula is proposed for the equivalent susceptance of a circular iris in a parallel plate waveguide when the TEM mode cylindrical wave is incident from the center of the iris. Schwinger’s variational method for a linear iris is generalized to the cylindrical case, and an approximate closed form formula is obtained which recovers the result of the linear iris when the radius of th...
