Abstract

The present paper is concerned with the reflection and transmission of elastic waves from a plane surface separating liquid half space and fluid saturated incompressible porous half space when longitudinal wave (P-wave) or transverse wave (SV-wave) impinge obliquely at the interface. Amplitude ratios of various reflected and transmitted waves are obtained. These amplitude ratios have been computed numerically for a specific model and results obtained are depicted graphically with angle of incidence of incident wave. It is found that these amplitude ratios depend on angle of incidence of the incident wave and material properties. A particular case of reflection at free surface of fluid saturated porous half space has been deduced and discussed. A special case in which fluid saturated porous half space reduced to empty porous solid is obtained and discussed from the present investigation.

Keywords

Porous solid, reflection, refraction, longitudinal wave, transverse wave, amplitude ratios.
