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.

The propagation characteristics of true and leaky or pseudo surface acoustic waves (TSAW and PSAW=LSAW) on (n11) GaAs-cuts, n=1, 2, 3 and 4, are theoretically calculated as a function of propagation direction. They include phase velocity (V), electromechanical coupling constant (K(2)), and attenuation factor (alpha) of wave propagation on a metallized surface. The results show that PSAW mode velocities are significantly higher than corresponding TSAW velocities, and for certain propagation directions the attenuation factor is extremely small (10(-5) dB/lambda). Highly coupled PSAW modes exist for propagation directions where the TSAW are very poorly coupled. For certain isolated directions, attenuation of the wave is null (alpha=0), PSAW becoming a non-leaky SAW with partial polarization. And in this case the corresponding TSAW are decoupled from the surface electric excitation. Analysis of relations between various modes (TSAW, PSAW and SSBW, surface skimming bulk wave) is made with the help of the effective surface permittivity function and the generalized slowness diagram. A coupling constant definition different from the usual 2DeltaV/V is used, its validity and application conditions are discussed.
