Abstract
In this paper, we present a study on the existence
of Bleustein-Gulyaev-Shimizu piezoelectric surface
acoustic waves in a two-dimensional piezoelectric phononic
crystal (zinc oxide, ZnO, and cadmium-sulfide, CdS) using
the plane wave expansion method. In the configuration
of ZnO(100)/CdS(100) phononic crystal, the calculated results
show that this type of surface waves has higher acoustic
wave velocities, high electromechanical coupling coefficients,
and larger band gap width than those of the Rayleigh
surface waves and pseudosurface waves. In addition, we find
that the folded modes of the Bleustein-Gulyaev-Shimizu
surface waves have higher coupling coefficients.
