Abstract
Dispersion relations of Lamb waves and shear horizontal (SH) waves propagating in the [100] and [110] directions of 0.67Pb (Mg13 Nb23) O3 -0.33PbTi O3 piezoelectric single crystal plate poled along [001]c were calculated. Multiple crossings between symmetric and antisymmetric modes appear due to the moderate anisotropy of these crystals. As frequency increases, the velocities for SH wave modes approach 2.88 and 0.88 mmμs, respectively, for waves propagating along [100] and [110] directions. These limiting velocities are the corresponding shear velocities of bulk crystals.
