Anisotropy of the electromechanical characteristics of SH-waves and lamb waves in yttrium aluminum borate single crystals

The anisotropy of the electromechanical properties of SH-waves and Lamb waves in yttrium aluminum borates, which are nonmagnetic representatives of the RMe$_3$(BO$_3$)$_4$ single crystals family (where R=Y, La-Lu; M=Fe, Al, Cr, Ga, Sc) with unique properties of magnetoelectrics and multiferroics, has been studied. In the process of the numerical simulation of the acoustic waves characteristics, the values of linear electromechanical constants of YAl$_3$(BO$_3$)$_4$ single crystals, previously measured by ultrasonic pulse echo and quasi-static methods, have been used.
