Analysis of reflection and transmission problems of waves in viscoelastic anisotropic media
黏弹各向异性介质中波的反射与透射问题分析

The waves propagating in viscoelastic anisotropic media are inhomogeneous. The modes of reflection and transmission are related not only to the velocity contrast, but also to the %Q% contrast of the correlated media. By modeling reflection and transmission of waves on the interface between viscoelastic anisotropic media using the pseudospectrum method, the results in the elastic anisotropic, viscoelastic isotropic, and elastic isotropic media are compared. Reflection and transmission coefficients are calculated and the effects of viscoelasticity and anisotropy of media on these coefficients are studied. By modeling the wave fields in a three-layer media model, the natures of reflected and transmission waves generated on two interfaces are investigated. In viscoelastic anisotropic media, qS waves have more inclination to attenuate than qP waves.
