Abstract
The characteristic frequency equation for SH-wave propagation in an anisotropic, inhomogeneous-layered structure lying between two isotropic, homogeneous half-spaces is obtained by applying the Thomson-Haskell matrix method. A particular case is studied to analyze the effects of varying anisotropy on SH-wave dispersion. Numerical analysis is performed for a representative set of data to distinguish between the cases of increasing, uniform, and decreasing anisotropy coefficien in the medium.
