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...

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...

Waveguide terahertz time-domain spectroscopy is demonstrated to have the sensitivity to characterize nanometer-thick water layers on the surfaces of a parallel-plate metal waveguide. The measured far-infrared absorption and index of refraction of the 20-nm water layers are in reasonable self-consistent agreement with those of bulk water.

A novel approach for the practical realization of feeding lines in connected array slots is presented. The proposed feed concept based on a parallel-plate waveguide (PPW) structure and allows simplifying unit cell design. When compared to typical integrated coaxial feed, PPW-based can reduce cost complexity array, by resulting lower number metal layers allowing large diameter vias. Two examples...

It is shown that there a better choice for solution of equations appeared in the above-mentioned paper from aspects convergence and CPU time.

Waveguide analysis is used to predict power levels received in a microcellular system in an urban environment. An Urban street with tall buildings on both sides is modeled by a plate parallel waveguide made of rough plates. The distribution of power among the waveguide modes tends to concentrate in the low order modes, at large distances from the source antenna. The waveguide–based model predic...
