“…As an example, amplitude response of a resonator on the θ = 55 o cut quartz is shown in Figure 2. Using the algorithm presented in [2], the STW parameters were changed until the measured and calculated amplitude responses were matched. The obtained parameters are shown in Table 1.…”

A surface transverse wave (STW) in quartz is interesting for application at high frequencies because of higher velocity than that of a surface acoustic wave (SAW). STW propagates along the plane of Y rotated cut perpendicularly to X axis of quartz and is described as θYX90 o , where θ is rotation angle. The plane should be covered with periodical electrodes and period of electrodes p should be equal to λ/2, where λ is the STW wavelength. So far, the STW were investigated only for the temperature compensated cut at θ ≅ 36 o . In this work we experimentally investigated three cuts with expected high first order temperature coefficients of frequency (TCF 1 ). For θ ≅ 43 o (ST cut for SAW propagating in the X direction), TCF 1 ≅ 35 ppm/ o C, was obtained. However, the second order coefficient TCF 2 ≅ -53 ppb/ o C 2 introduced relatively large nonlinearity to the frequency changes against temperature. For the new cuts at θ ≅ 47 o and θ ≅ 55 o , the TCF 1 of about 45 ppm/ o C and 71 ppm/ o C respectively, were obtained. TCF 2 = 0 was obtained for both cuts. The results show that the STW on the new cuts of quartz are attractive for application in wireless temperature sensors.

“…During that period, investigations regarding the propagation of SSBW on shallow corrugation surfaces were widely conducted (Auld, Gagnepain, 1976;Auld, Yeh, 1979), establishing the fundaments of STW. Later on, the investigations on the differences between STW and Rayleigh wave (Auld et al, 1982), the propagation characteristics of STW under period and non-period structures (Baghai-Wadji et al, 1988;Danicki, 1983;Ronnekleiv, 1986;Thompson, Auld, 1986), and the development and fabrication of STW-based resonators (Auld, Thompson, 1987;Bagwell, Bray, 1987;Flory, Baer, 1987;Strashilov et al, 1997) have been carried out as well. Recently, related micro-strain sensors (Fu et al, 2016), torque sensors (Ji et al, 2016), vapor sensors (Stahl et al, 2018) and resonators (Doberstein, Veremeev, 2019) have been reported.…”
