Abstract :
The main achievements in the development of the diffraction radiation oscillator (DRO) are brought together; the IRE NASU have created various DRO versions which at the accelerating voltage of 2.5 - 4.0 kV continuously span the whole mm wave region. With the feed under 500 W, the output power level varies from less than 1 W in the short-wave part of the mm wave region to tens of watts in the long-wave part. We seek to report the progress made during the last three years in further understanding DRO physics, in the extension of combined (mechanical and electronic) frequency tuning and in the enhancement of the DRO interaction efficiency
