Abstract: | Regimes of wideband chaotic microwave generation have been studied in a self-oscillating ring system with a nonlinear delay
line, in which magnetostatic backward volume waves (MSBVWs) are excited. It is established that a change in length of the
delay line influences on its amplitude and phase nonlineartity, thus making it possible to control the characteristics of
the chaotic microwave signal generated in the ring. It is demonstrated for the first time that a wideband chaotic microwave
signal with a continuous spectrum and a nearly Gaussian probability density distribution can be generated by exciting MSBVWs
in a self-oscillating ring system with a nonlinear delay line based on single ferromagnetic film. |
