Description
Summary:A multifunctional microwave spin-wave device utilizing a ferrite-film magnonic crystal is reported. A principal of operation of the device is based on a nonlinear frequency shift and a nonlinear damping of the carrier spin waves propagating in the magnonic crystal. The device performs several functions of microwave signal processing, namely, enhancement of signal-to-noise ratio, limiting or suppression of high-power signals, and power-dependent phase shift.
