REFLECTION/REFRACTION OF SH-WAVES AT A CORRUGATED INTERFACE BETWEEN TWO DIFFERENT ANISOTROPIC AND VERTICALLY HETEROGENEOUS ELASTIC SOLID

We investigate the reflection and transmission of SH-waves at a corrugated interface between two different anisotropic, heterogeneous elastic solid half-spaces. Both the media are assumed to be transversely isotropic and vertically heterogeneous. Rayleigh’s method is followed and expressions for the reflection and transmission coefficients are obtained in closed form for the first-order approximation of the corrugation. It is found that these coefficients depend on corrugation and are affected by the anisotropy and heterogeneity of the media. Numerical computations for a particular model have been performed. 1
