Wave reflection in PMN-PT piezoelectric half-space

Abstract

This paper investigates SH waves reflection in the PMN-PT piezoelectric half space. The PMN-PT piezoelectric crystals are being polarized along [011]c of the cubic reference directions so that the effective macroscopic symmetries is mm2. The surface of the PMN-PT piezoelectric half spaces is mechanically free, and the electric boundary conditions are electrically open and shorted. The results show that the reflection coefficients depend on the cutting angle. The obtained results may be useful for the application of the high-frequency surface acoustic devices.
