title: On the existence of localized shear horizontal acoustic waves in a piezoelectric plate with two semi-infinite same/different coatings.
abstract: In this paper, the existence theorem of localized shear horizontal acoustic waves in a piezoelectric plate with two semi-infinite same/different coatings is established. Some properties of the waves in the waveguide structures are also discussed. The results show that the waveguides have some advantages and provide more choice for the designs of acoustic devices.
