【 摘 要 】

Development of a microwave dynamical chaos in an active ring oscillator based on a ferromagnetic film upon a gradual increase of the ring gain has been studied. It was demonstrated that the transition of the system from steady-state to chaotic dynamics is in good agreement with the Ruelle-Takens scenario. The attractors of the dynamic system were reconstructed from the experimentally measured waveforms, and a numerical analysis of their parameters was made.
