Abstract : Propagation properties of the quasi-longitudinal leaky surface acoustic wave (QLLSAW) along different directions on Y-rotated cut quartz substrates, such as on the 34o , 36o , 42o Y-rotated cut, are investigated. The advantages of the QLLSAW along some directions include low propagation attenuation (less than 10-4 dB/λ), small power flow deviation and high phase velocity which can be up to 7000 m/s. A novel propagation direction of the quasi-longitudinal leaky surface acoustic wave with the theoretical temperature coefficient of delay of 0.508 ppm/o C is proposed.
