Main directions of activity Methods and technique

Development of methods and technique of microwave spectroscopy in millimeter and submillimeter wave range

In particular, a submillimeter-wave spectrometer with Backward Wave Oscillators (BWO) and acoustical detection (RAD spectrometer), systems of phase locking of the BWO frequency and then frequency synthesizers of millimeter and submillimeter wave ranges, Terahertz video-spectrometer with BWO and LHe cooled bolometer, fast scanning digital millimeter and submillimeter wave range frequency synthesizers with switching time of 200 ns without phase jump and based on them precision resonator spectroscopy in millimeter and submillimeter wave range have been developed. Our products and developments are widely used in different laboratories all over the world.

Commercial millimeter-wave frequency synthesizers, developed jointly with "KVARZ" (Institute of Electronic Measurements, Nizhny Novgorod) are used in the Laboratories of the USA, Germany, France, Italy, Japan, Canada, China. Based on the techniques initially elaborated for spectroscopic purposes, fundamental and applied metrics of the millimeter and submillimeter wave ranges are developed. Recently, a wide scope of applications of the new resonator spectroscopy were developed for monitoring atmosphere and technological processes.
