Abstract

Tunable backward-wave oscillators (BWO) covering the frequency range of 180- 370 GHz with an output power below 100 mW are used for the study of wave transmission and reflection in composite layered structures. Techniques for transparent and lossy liquid absorption and refraction measurements (blood plasma, ethanol, water solutions etc.) are presented. Besides of the solid- liquid structures which are applicable in phase shifters and attenuators, semiconductor-metal structures with p-i-n junctions are examined as high-speed modulators.
