La3Ga5.5Ta0.5O14 (LGT) is a new piezoelectric material with superior electromechanical properties and high Q·f product. Transverse-wave splitting behavior of LGT was observed in the acoustic velocity measurements. The velocities of the two shear waves propagating in Y-(010) direction are very close and they cannot be separated completely. This has a tremendous influence on determining the correct velocity of the shear modes. It is proposed that the singular value decomposition (SVD) technique… CONTINUE READING
