Investigation of the stochasticity of beam generators using the functional map method

Certain distributed dynamic systems describing the well-known beam generators of UHF oscillations are organized in a very simple way: the nonlinear function, which determines the current state of the system with respect to its behaviour in the past, is represented as a composition of the linear function and the nonlinear finite dimensional map. This property made it possible to find the mechanisms of automodulation and stochasticity of the signals from beam generators and to define a corresponding range of parameter values.
