Magnetoelastic Rayleigh-Type Surface Wave on a Tangentially Magnetized YIG Substrate

Abstract

The propagation characteristics of an exchange‐free magnetoelastic Rayleigh‐type surface wave propagating on a YIG substrate in the direction of a tangentially applied bias field are treated. The surface wave is found to be of the leaky‐wave variety within a band of frequencies given approximately by the magnetostatic bulk‐wave spectrum, rather than of the bound surface‐wave variety occurring outside this frequency band.
