RESUMO
A self-generation of chaotic dissipative spin-wave multisoliton complexes has been observed experimentally. Localized in time, these patterns are formed in a passively Q-switched and mode-locked magnetic film feedback ring due to the competing three- and four-wave nonlinear spin-wave interactions. Such competition induces a modulation instability that leads to the formation of incoherent one-color four-wave bound solitons embedded in chaotic three-wave solitonlike pulses. The development of a symmetry-breaking instability causes a transition from incoherent one-color four-wave bound solitons to chaotic multicolor ones.
RESUMO
In this Letter, we report for the first time on the experimental observation of the generalized synchronization regime in the microwave electronic systems, namely, in the multicavity klystron generators. A new approach devoted to the generalized synchronization detection has been developed. The experimental observations are in the excellent agreement with the results of numerical simulation. The observed phenomena gives a strong potential for new applications requiring microwave chaotic signals.
