Abstract :
The theory is developed of interfacial acoustic waves (IAW) in bi-crystalline piezoelectric structures of two particular types. A number of general theorems concerning the existence of subsonic, leaky, and "supersonic" IAW has been proved. The reflection of bulk waves near a leaky IAW branch has also been studied. Some numerical results on IAW propagation and reflection of bulk waves have been presented.
