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.

The paper presents the results related to the construction of a model based on the coupled waves to describe the characteristics of magnetostatic waves passing through the structure on the basis of one-dimensional magnon crystal at various geometric parameters of the structure and at finite values of the input power.
