Flare coupled metal parallel-plate waveguides for high resolution terahertz time-domain spectroscopy
(AIP Publishing, 2010-12-03)
We report on a new coupling scheme for high resolution terahertz spectroscopy of microcrystalline films using parallel-plate waveguides. Metal flares are used to couple the terahertz radiation into and out of the waveguide. ...
High-Q terahertz Bragg resonances within a metal parallel plate waveguide
(AIP Publishing, 2009-03-06)
One-dimensional (1D) Bragg waveguides are demonstrated at terahertz (THz) frequencies. Lithographically made 1D symmetric and asymmetric dielectric gratings on metallized high conductivity Si chips are incorporated within ...
Line narrowing of terahertz vibrational modes for organic thin polycrystalline films within a parallel plate waveguide
(AIP Publishing, 2006-12-19)
Waveguide terahertz time-domain spectroscopy is used to demonstrate the narrowing of vibrational lines for a thin polycrystalline film of 1,2-dicyanobenzene in a parallel plate metal waveguide. When compared to corresponding ...
Terahertz two-cylinder waveguide coupler for transverse-magnetic and transverse-electric mode operation
(AIP Publishing, 2011-02-18)
We report the coupling and guiding of broadband terahertz radiation using a two-cylinder waveguide coupler. For the transverse electromagnetic TEM (TM0) geometry, the two opposing metal cylinders exhibit an amplitude ...
