Radiation patterns associated with the scattering from viscoelastic inclusions

Shahpoor Moradi, Kristopher A. H. Innanen

In this report we obtained the radiation patterns associated with the scattering of seismic waves from five viscoelastic inclusions; density, P- and S-wave velocities and quality factors for P- and S-waves. We show that the polarization and slowness of viscoelastic waves are complex. Basically the radiation patterns from elastic and anelastic inclusions are given by the scattering potentials which are the amplitude of the spherical scattered waves from scatter points. We show that the scattering potentials are complex functions of averages in phase and attenuation angles.
