Electro-acoustic slip and gap waves in piezoelectric structures of general anisotropy

Abstract

The existence conditions have been investigated for the subsonic acoustic waves guided by different types of contact between identical piezoelectric crystals of arbitrary symmetry: 1) Perfect sliding contact; 2) vacuum gap separating the two crystals. In addition, we have analyzed specific features of the bulk wave resonance reflection in gap structures stipulated by simultaneous excitation of two leaky modes.
