Non-stationary Love waves of $SH$-type in anisotropic elastic medium. Kinematic approach

In this work the author proceeds with the study of Love waves propagation in anisotropic elastic media. These waves are a counterpart of transverse surface $SH$ waves in the isotropic case. Necessary conditions indispensable to the existence of Love waves of this polarization are deduced in the case of the arbitrary surface of an anisotropic elastic body. The employed algorithm is illustrated by some particular anisotropic cases. The space-time ray method is involved to research Love waves propagation for those types of anisotropic media whose eikonal equation is valid on the surface. Bibliography: 7 titles.
