Love waves in a sedimentary layer lying over an anisotropic inhomogeneous half space

Summary The effects of anisotropy and inhomogeneity on the propagation of Love waves in a sedimentary layer, overlying the inhomogeneous and transversely isotropic half space, are studied in this paper. The results of numerical analysis show an appreciable variation of phase- and group-velocity of Love waves in low frequency region compared to high frequency region due to the presence of transverse isotropy and inhomogeneity in the half space. The higher values for phase velocity are found for the increasing values of anisotropy factor as well as for the greater power of density variation. However, the presence of higher anisotropy factor and inhomogeneity in the half space reduce group velocity considerably in the lower frequency region.
