【Abstract】 The group velocity and polarization vector for qSV wave are studied in transversely isotropic media with vertical axis of symmetry, the exact and approximate formula for the calculation of group velocity and polarization are given in the paper, and the reliability of the replacement to the algebraic complexity of the exact formula with the simplified approximate formula is discussed. In the last, we present velocity anisotropic factor, polarization and their corresponding deviation between polarization and its phase normal for qSV wave in several commonly anisotropic materials.更多还原
