This paper presents theoretical and experimental study of QSH waves propagating in thin plates of lithium niobate. The electromechanical coupling coefficient K2 has been calculated as a function of plate thickness and propagation direction for all main crystallographic cuts. Y-cut and X-propagation for which K2 may be more than 30% were chosen for our experiments. We have measured K 2 as a function of plate thickness and have obtained a good agreement with theory. The extremely large value of K2 opens possibility of realizing devices whose parameters can be controlled by electrical boundary conditions. We have studied SH waves propagating in the presence of a conducting electrode. It is found that by varying the gap between plate and electrode, the phase shift for a 3.2 MHz delay line can be varied by as much as 240°. We have also studied the influence of a thin layer of arbitrary conductivity on the velocity and attenuation of the QSH wave. Analysis show that the variations in these parameters can be as high as 18% and 4 dB/λ for a change of surface conductivity from 10-7 to 10-5 S
