Relativistic Backward-Wave Oscillator with Parallel Wave Interaction

详细

We study operation of a backward-wave oscillator (BWO) in the regime of parallel amplification of rotating waves with different azimuth indices. It is shown that in the linear case, the use of the parallel wave interaction principle allows one to enhance the BWO gain significantly as compared with a classical backward-wave oscillator. An option for using parallel amplification in high-power sectioned amplifiers is proposed.
