Cold test validation of novel slow wave structure for high-power backward-wave oscillators

U Chipengo, NK Nahar… - IEEE Transactions on …, 2016 - ieeexplore.ieee.org
Previous work presented the concepts of mode dominance reversal using a novel slow
wave structure (SWS). An example application of this mode reversal was a backward-wave …

A study of velocity-tapered slow wave structures for high-efficiency backward wave oscillators

U Chipengo, NK Nahar… - IEEE Transactions on …, 2017 - ieeexplore.ieee.org
In this paper, we present a comprehensive study of multisection, velocity-tapered slow wave
structures (SWSs) for highly efficient backward-wave oscillators (BWOs). The SWS velocity …
