In the nonlinear drift-waves driven by a sinucoidal wave, every mode has a resonance regime correspondingly in the parameter space of the driving frequency and strength. Feeding of the applied wave energy causes the transition of a resonant negative-energy mode to positive-energy one. This transition is relevant to the development of bistability of the system in the corresponding regime.
