Bragg reflection of surface electroacoustic shear waves
Abstract
Bragg reflection of surface electroacoustic shear waves in piezoelectric media is analyzed and the width of the suppression band, which depends on the excitation level, is determined. The piezoelectric halfspace is assumed to have an axis of sixthorder symmetry and a metallized boundary surface with an inertia load small periodic perturbation. An analysis of the dispersion equation and a correlation with reflection of volume electroacoustic shear waves reveals that, owing to the small difference between the respective velocities, the Bragg suppression band for quasivolume surface waves will merge with the range of wave attenuation by scattering into the volume.
