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 ...
Underlying terahertz vibrational spectrum of explosives solids
(AIP Publishing, 2008-07-08)
Using waveguide terahertz time-domain spectroscopy, we demonstrate the measurement of the underlying terahertz vibrational spectrum of the explosive solids hexahydro-1,3,5-trinitro-1,3,5-triazine, and 2,4,6-trinitrotoluene. ...
