CHAOTIC MICROWAVE PULSE GENERATION IN WIDEBAND SPIN­WAVE AND VACUUM OSCILLATORS OF CHAOS UNDER EXTERNAL PERIODICAL INFLUENCE

The non­autonomous generation of chaotic microwave pulses in the wideband chaos oscillators is experimentally investigated. Nonlinearity of a spin­wave transmission line is a cause of chaotic dynamics of the spin­wave chaos oscillator and nonlinearity of a TWT amplifier is a cause of chaotic dynamics of the other chaos oscillator. It is shown, that in both cases, the generation of chaotic microwave pulses is observed when an external pulse­modulated microwave signal has a certain power level and its carrier is detuned from a central frequency of a chaotic signal.
