New acoustic plate modes (APMs) with quasi-shear-vertical (QSV) and quasi-shear-horizontal (QSH) polarizations are found numerically in piezoelectric, nonpiezoelectric, and isotropic plates with free faces. Experimental verification of the modes is accomplished for ST,X-quartz plate, as an example. Similar to the modes with quasi-longitudinal displacement reported recently, the new counterparts exist when their velocities vAPM are close to the velocities vBAW of the relevant bulk waves, the… CONTINUE READING
