Some exact forms for viscoelastic reflection coefficients
Shahpoor Moradi, Kristopher A. H. Innanen
An explicit analytical form of the scattering matrix for Homogeneous Isotropic Linear Viscoelastic (HILV) continuum is obtained. The reflection and transmission are the complex function related to the P- and S-velocities and corresponding quality factors QP and QS. The real part is the elastic scattering potential and the imaginary part is the term induced by the anelasticity of the medium. Linearized reflection coefficients can be used for viscoelastic AVO/AVA and full waveform inversion.
