Chaotic signal generation from relativistic backward-wave oscillator

In this article, a numerical simulation was done for broadband signal generation in chaotic regimes of relativistic BWO, where a single parameter model was introduced base on nonlinear theory, and 1D nonstationary code was also used. Using relativistic high current electron beam, the BWO enables to generate microwaves up to 10s of gigawatt-level and 50% in efficiency.
