| Abstract: | A theoretical and numerical analysis is made of the dynamics of nonlinear electron-beam scattering of a wave reflected by
the emitting device of a plasma oscillator. It is shown that a counterpropagating plasma wave can interact nonlinearly with
other waveguide modes of the system and with charge-density beam waves, leading to changes in the operation of the oscillator.
It is established by means of a numerical simulation that the generation efficiency is reduced as a result of scattering of
the counterpropagating wave and stimulated emission of a strong-potential plasma wave with phase velocity v
ph=ω/k
