Keywords:Reflection and transmission of elastic waves
A study of the reflection and transmission of elastic waves from a plane surface separating a viscous liquid half space and a fluid saturated porous half space is presented when a longitudinal or a transverse wave impinge obliquely at the interface. Amplitude ratios of various reflected and transmitted waves are obtained using suitable boundary conditions at the interface. The amplitude ratios have been computed numerically for a particular model and the results obtained are presented graphically. It is observed that the amplitude ratios depend not only on the angle of incidence of the incident wave, but also on material properties of the medium through which the waves traversed. Special cases with empty porous half space medium and inviscid liquid half space has been obtained from the present investigation.
