摘要：

A new high-phase-velocity leaky surface acoustic wave (SAW) mode, which was predicted by computer simulation, was confirmed experimentally to exist on both LiTaO3 and LiNbO3. The Euler angles of the propagation direction are (90 degrees, 90 degrees, 31 degrees) on LiTaO3 and (90 degrees, 90 degrees, 37 degrees) on LiNbO3. One-port SAW resonators were produced to confirm these modes. The phase velocity of the mode on LiTaO3 (90 degrees, 90 degrees, 31 degrees) is 6250 m/s, and that on LiNb O-3 (90 degrees, 90 degrees, 37 degrees) is 7170 m/s. The temperature coefficient of the resonance frequency on LiTaO3 (90 degrees, 90 degrees, 31 degrees) is -30 ppm/degrees C, and that on LiNbO3 (90 degrees, 90 degrees, 37 degrees) is -30 ppm/degrees C.
