Study of miniaturized low-voltage backward-wave oscillator with a planar slow-wave structure

The development of the terahertz frequency range is one of the priority problems of modern vacuum microwave electronics. For increasing power and efficiency of such devices, it is favorable to use spatially developed slow-wave structures (SWSs) and electron beams with a large cross section. For miniaturization of vacuum-tube devices, reducing of the accelerating voltage becomes a problem of principal importance. In this respect, planar SWSs on dielectric substrates are very promising.
