Abstract

In the present work, using the well-known numerical procedure for SAW calculation in arbitrary crystals the gyroscopic effect is investigated. To take into account the medium rotation the Coriolis and centrifugal forces are introduced into the piezoelectric medium equations of motion. As a result of the standard procedure, the SAW velocity is calculated as a function of the medium rotation rate about each coordinate axis. A shift of such velocity due to rotation is determined for isotropic Al, STX-quartz, 128Â°YX-LiNbO₃, YZ-LiNbO₃, X112Â°Y-LiTaO₃, and Z-cut of AlN substrates.
