摘要:

This article analyzes theoretically the ‘‘in‐line field’’ scheme and the ‘‘crossed‐field’’ scheme for acoustic excitation of an acoustic superlattice for both resonators and transducers. The electrical impedance and the admittance are deduced and the electromechanical coupling coefficients are calculated. ©1996 American Institute of Physics.
