Abstract
The frequency dependencies of the transmission coefficient of surface magnetostatic waves (SMSW) propagating in subwavelength magnonic structures obtained by depositing of 1D and 2D thin-film metastructures based on a permalloy film 40 nm thick onto the surface of yttrium iron garnet (YIG) film were experimentally studied. Such structures in the frequency range 1–10 GHz (typical for the study of SMSW in YIG films) lead to modulation of attenuation and the effective internal magnetic field in the YIG film. The possibility of controlling the parameters of the bandwidth of the SMSW by the choice of the direction of magnetization in the plane of the structures relative to their axis of symmetry is shown.
