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.

Investigations of the hf noise generation in ire of academy of sciences of ussr at 1962–1967 years – the beginning of the new science direction

This paper is devoted to the noisetron creation history in 1967 – the chaotic oscillations oscillator consisted of two traveling wave tubes (TWT), contacted successively in ring. It is shown that the noisetron creation is the result of the work on HF noise generation in the systems electron-ion plasma–electron stream, which was fulfilled in V.Ya. Kislov’s laboratory. This work was initiated by the theoretic investigations on the interaction of electron stream with electron-ion plasma, fulfilled by V.Ya.Kislov in the period of 1956...1960 years.
