Abstract (in english)
   Amplitudes of PP spherical waves reflected at a plane interface between two homogeneous viscoelastic media are studied. Mostly, the plane-wave reflection coefficients have been used in such studies in the past. For viscoelastic media, however, the meaning of plane-wave reflection coefficients meets some fundamental difficulties. For this reason, the spherical-wave reflection coefficients, corresponding to a point source, are used here. The spherical-wave reflection coefficients were introduced for perfectly elastic media and were evaluated by approximate asymptotic high-frequency methods. They can be, however, also calculated by highly accurate reflectivity method, even for viscoelastic media.
