A field theory for the magnetostatic surface wave (MSSW) reflectivity of a single shallow groove etched on top of an epitaxial YIG film is presented. Computed reflection characteristics are obtained for the case in which the surface of the YIG film is metallized after the groove is etched. It is found that the MSSW reflectivity of a groove is significantly larger than the SAW reflectivity of an equivalent groove on a LiNbO3 substrate.
