摘要: The features of chaotic spin waves in magnetic film feedback rings were studied. Experiments made use an yttrium iron garnet thin film-based active ring. excitation relied on the three-wave interactions short- and long-wavelength backward volume waves. evaluated through calculation ambiguity functions (AFs) measured signals. results indicate that one can tune AF properties via ring gain. In particular, increase gain leads to suppression side lobes diagram, both number amplitude, but produces negligible effects main peak. cross are consistent with nature These potential oscillators for radar applications.
