ABSTRACT

It is shown that the ferrite's high-frequency eigen waves are excited in the case of low-frequency random modifications of ferrite parameters. The excitation takes place as a result of development of stochastic parametrical instability. The considered mechanism of excitation of these high-frequency waves is rather general and has opened up a new way to transform energy of low-frequency oscillations to energy of high-frequency waves. In addition, the considered mechanism allows one to transform energy of noise oscillations to energy of a coherent radiation.
