Vibration velocity characteristics under short burst excitation. (a) Vibration velocity at the waveguide tip, PZT surface and (b) calculated amplification ratio under 5-cycles short burst excitation. In (c) the waveform at the waveguide tip under 10 Vpp excitation is compared between simulation and experiment.
