Characteristics of fundamental acoustic wave modes in thin piezoelectric plates

TL;DR: In this article, the characteristics of the three lowest order plate waves propagating in piezoelectric plates whose thickness h is much less than the acoustic wavelength lambda are theoretically analyzed, and it is found that these waves can provide much higher values of electromechanical coupling coefficient K(2) and lower values of temperature coefficient of delay (TCD) than is possible with surface acoustic waves.
