Optical tunneling of single-cycle terahertz bandwidth pulses
(American Physical Society, 2001-08-27)
We report time-domain measurements with subpicosecond resolution of optical tunneling of terahertz electromagnetic pulses undergoing frustrated total internal reflection. Measurements of the transmitted electromagnetic ...
Time resolved synthetic aperture terahertz impulse imaging
(AIP Publishing, 2001-12-31)
Using a well characterized terahertz (THz) impulse ranging system we demonstrate broad bandwidth imaging at THz frequencies using an inverse synthetic aperture deconvolution technique. The system demonstrates millimeter ...
Properties of surface waves determined via bistatic terahertz impulse ranging
(AIP Publishing, 2001-02-19)
A bistatic terahertz impulse ranging system has permitted the full isolation and direct measurements of the surface wave loss and dispersion for terahertz frequencies on a dielectric cylinder. This system permits ranging ...
Characterization of thin polymer films using terahertz time-domain interferometry
(AIP Publishing, 2001-08-06)
An interferometer for broadband single-cycle THz pulses is developed based on the Michelson configuration. Total internal reflection of THz pulses in high-resistivity silicon prisms provides a nearly 180° phase shift of ...
