Observation of a new type of THz resonance of surface plasmons propagating on metal-film hole arrays
(American Physical Society, 2004-11-04)
Highly conducting metal-film subwavelength hole arrays, lithographically fabricated on high-resistivity silicon wafers in optical contact with thick silicon plates, have been characterized by terahertz time-domain spectroscopy ...
Integrated waveguide-coupled terahertz microcavity resonators
(AIP Publishing, 2007-11-09)
We demonstrate integrated square terahertz microcavity resonators side coupled to waveguides. We present the microcavity transmission spectra for different resonator sizes and coupling strengths. The measured quality factors ...
Adiabatic compression of terahertz waves using metal flares
(AIP Publishing, 2010-05-14)
We report on the adiabatic free-space coupling of broadband terahertz (THz) radiation through a subwavelength gap using metal flares. Amplitude coupling ratios better than 30% are obtained by optimizing the curvature. This ...
Capacitance free generation and detection of subpicosecond electrical pulses on coplanar transmission lines
(Institute of Electrical and Electronics Engineers, 1988-02)
Based on a reanalysis of previous work and new experimental measurements, we conclude that the parasitic capacitance at the generation site is negligible for sliding contact excitation of small dimension coplanar transmission ...
Echo behavior in ruby
(American Physical Society, 1968-01-08)
Electromagnetic shock waves from transmission lines
(American Physical Society, 1987-10-12)
We have observed subpicosecond electrical pulses to propagate on 5-pm coplanar transmission lines at velocities faster than the phase velocity in the underlying dielectric. This situation produces an electromagnetic shock ...
