Love wave synchronous resonator on quartz with SiO2 layer

Love wave and surface transverse wave are two independent acoustic modes propagating in the area of periodical electrodes on 35°YX90° cut quartz with a SiO₂ layer. A synchronous resonator and the scattering matrix method were used for determination of these waves´ parameters. For the Love wave mode, at a frequency of about 492 MHz, insertion loss, loaded and unloaded quality factors of about 11 dB, 5500 and 7800, respectively, were obtained. This resonator is promising for applications in sensors.
