Parallel-Plate Waveguide-Feeding Structure for Planar-Connected Arrays
نویسندگان
چکیده
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 design, this new concept, are presented; one consists single-polarized slot, covering band from 70 140 GHz; another example referring single- dual-polarized slot 2–8 GHz range.

Spatial mode-locking in three dimensions can be achieved in a slab waveguide array architecture. This study focuses on using the resulting robust and self-starting light bullet formation for photonics applications. Specifically, light bullets can be manipulated through a simple electronically addressable spatial gain dynamics. By applying gain ramps in time and/or space via electronics technolo...
متن کاملObservation 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...
