Abstract
When a homogeneous plane longitudinal or P-wave in a fluid is incident on a fluid-solid interface at a supercritical angle, it generates an inhomogeneous refracted P-wave in the elastic solid. In this study an inhomogeneous elastic P-wave is demonstrated to have components parallel to and perpendicular to the direction of propagation, exhibiting elliptical polarization characteristics. While the wavefield remains irrotational, the traveling velocity along the propagation direction is slightly less than that of a homogeneous P-wave.
