Abstract
The frequency dependences of the transmission coefficient of surface magnetostatic waves (SMSW) propagating in subwavelength magnonic structures obtained by deposition of 1D and 2D thin-film metastructures based on a 40-nm-thin permalloy film on the surface of an yttrium–iron garnet (YIG). These structures lead to a modulation of the damping and the effective internal magnetic field in the YIG film in the frequency range 1–10 GHz typical for studying SMSW in YIG films. The possibility of controlling the parameters of SMSW forbidden band by choosing the magnetization direction in the structure plane with respect to its symmetry axes.
