Ceramic dielectric mirrors for the terahertz range

Applied Optics, 2006
We have produced a rigid dielectric terahertz mirror by tape casting and sintering 25 stacked ceramic layers of alumina and alumina-zirconia. Our structure shows a pronounced stop band between 0.3 and 0.38 THz. The experimental data agree well with transfer matrix calculations.

Klinoorbictron - terahertz range oscillator

2010 INTERNATIONAL KHARKOV SYMPOSIUM ON PHYSICS AND ENGINEERING OF MICROWAVES, MILLIMETER AND SUBMILLIMETER WAVES, 2010
Based upon the developed program that allows for the deposition of current on the slow-wave structure (SWS) the optimal parameters of a 3-mm wave orbictron and klinoorbictron operating at a 3-kV electron beam voltage have been calculated. The beam stratification effect in an orbictron has been studied.

Terahertz spectroscopic investigations of leather in terahertz wave range

SPIE Proceedings, 2012
Pulsed THz time-domain spectroscopy is a coherent technique, in which both the amplitude and the phase of a THz pulse are measured. Recently, material characterization using THz spectroscopy has been applied to biochemicals, pharmaceuticals, polymers and semiconductors and has given us important information.

Terahertz-range quantum well photodetector

SPIE Proceedings, 2005
We have designed and fabricated GaAs/AlGaAs QWIP photodetector for THz range of spectrum (3THz, 100 μm). To evaluate suitability of this type of detector for real-time THz imaging, a prototype of a small array have been built by integrating detector elements with cryogenic readout electronics.
