Parallel Plate Waveguide

Click here to go to our main waveguide page

New for January 2010! Parallel plate waveguide supports wave propagation (even a low-loss TEM mode), but has no sidewalls like rectangular waveguide. It is becoming an enabler for teraHertz systems.

A 2010 paper entitled Superfocusing terahertz waves below Lambda/250 using plasmonic parallel-plate waveguide by Hui Zhan, Rajind Mendis, and Daniel M. Mittleman explains the degree of energy confinement increases exponentially with decreasing plate separation.

Dr. Mendis is a fan of Microwaves101 and sent us this paper. You can obtain a free copy on the Optics Society of America's web site.

This page is awaiting more content from readers like Dr. Mendis!
