“…STW propagation has been examined on corrugated surfaces, for groove depths h/"A from 0.75-1.37 percent and 501 or 701 grooves [315], as well as with aluminum strip gratings of various height-to-period ratios [313]. STW propagation under a metal-strip grating differs from that under a grooved one [313].…”

Applications of surface acoustic wave (SA W) and shallow bulk acoustic wave (SBA W) devices are reviewed. SA W-device coverage includes delay lines and filters operating at selected frequencies in the range from about 10 MHz to 11 GHz, modeling with singlecrystal piezoelectrics and layered structures, resonators and lowloss filters, comb filters and multiplexers, antenna duplexers, harmonic devices, chirp filters for pulse compression, coding with fixed and programmable transversal filters, Barker and quadraphase coding, adaptive filters, acoustic and acoustoelectric convolvers and correia tors for radar, spread spectrum, and packet radio, acoustooptic processors for Bragg modulation and spectrum analysis, real-time Fourier-transform, and cepstrum processors for radar and sonar, compressive receivers, Nyquist filters for microwave digital radio, clock-recovery filters for optical fiber communications, fixed-, tunable-, and multimode-oscillators, and frequency synthesizers, acoustic charge transport (ACT), and other SA W devices for signal processing on gallium arsenide, SA W sensors, and scanning acoustic microscopy. SBA W-devices applications include gigahertz delay lines, surface transverse wave resonators employing energy-trapping gratings, as well as oscillators with enhanced performance and capability.

“…Auld et al have proposed a theoretical approach for modelling the STW resonances on corrugated isotropic plates of finite thickness. 12 Ten years after, Danicki et al have also proposed a similar analysis, 13 even extended to double side corrugated isotropic plates, but none of these studies has provided quantitative results for the design of STW devices on crystal plates of finite thickness.…”

A theoretical model of transverse waves propagating on piezoelectric plates of finite thickness under metal strip gratings is proposed. Different mechanical and electrical boundary conditions are considered and their influence on the propagation characteristics of the waves is emphasized. In all the cases, the dispersion curve relating the angular frequency to the wave number exhibits more than only one stopband as found in the usual analysis of surface transverse waves on semi-infinite substrates. This model has been used to calculate the resonance frequencies of synchronous devices on AT-cut and Z-cut quartz plates. These theoretical predictions are compared to experimental results obtained using synchronous devices built on 128-m-thick Z-cut plate of quartz and AT-cut plate of quartz and operating at frequency range 80-150 MHz.

“…Coupling between forward and backward waves can be described by expanding the fields in Bloch modes of the periodic structure, and satisfying the boundary conditions on the stress field at the interface between the metal and the substrate surface [18, 19,20]. Once the Bloch mode amplitudes and propagation constants are known, the coupling in a finite length grating can be solved by taking a suitable linear combination of grating modes and satisfying the boundary conditions for the wave amplitudes at the ends of the gratings.…”

Surface transverse wave (STW) resonator devices have been designed and fabricated on rotated Y cuts of quartz, with wave propagation perpendicular to the X axis.Packaged devices with center frequencies of 500 and 632 MHz show insertion loss less than 6 d B in a 50 ohm system.Unloaded Q is typically greater than 10,000. Devices at 1726 MHz show packaged insertion loss as low as 10 dB and unloaded Q as high as 5600. Temperature behavior was studied. STW resonators were found to exhibit significantly greater power-handling ability than SAW resonators with comparable design parameters and electrical performance in a comparison study.Device phase noise measurements indicate that STW resonators' noise improves when driven with high incident power.Single sideband device phase noise less than -135 dBc/Hz at 1 H z offset was achieved.
