Abstract :
The nonlinear nonstationary 1D theory of miniature low-voltage Backward-Wave Oscillator (BWO), taking into account velocity distribution in electron beam is considered. The phenomenon of automodulation threshold shift when velocity spread increases is investigated. The developed code on BWO numerical simulation can be readily applied to different kind distributions
