In this article, we report on the Fano resonance characteristics tunability in a coupled system of magnonic stripes and resonators by variating the geometric parameters, the magnitude of the coupling between them, and the intensity of spin waves (SWs). Using numerical integration of the coupled-wave equation system, we calculated the transfer characteristics of the considered system and the parameters of Fano resonance considering the cubic nonlinearity of magnetic media. We demonstrate the features of constructive and destructive interference of SWs at Fano resonance. Our results reveal the mechanism of the SW spectra control of the nonlinear Fano resonance (asymmetry coefficient and resonance frequency shifts) via the intensity of SW.
