Dynamics of three wave stochastic decays in nonlinear matter
In the present work the transition of decay instability into stochastic regime in a nonlinear media is analyzed for a magnetoactive plasma and for the ferrite magnetized to the saturation level. It was shown that parameter of nonlinear interaction can be anomalously strong near the resonance frequ...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | In the present work the transition of decay instability into stochastic regime in a nonlinear media is analyzed for a
magnetoactive plasma and for the ferrite magnetized to the saturation level. It was shown that parameter of
nonlinear interaction can be anomalously strong near the resonance frequencies: electron and ion cyclotron
frequencies in the magnetoactive plasma and ferromagnetic frequency in ferrite. It was shown that the threshold
value of decaying wave amplitude, when transition into stochastic regime takes place, is reducing when frequency of
the wave with the lowest frequency is decreasing. |
