Abstract

The reflectivity at the interface at two solid half-spaces was extensively studied in the past. Theoretical calculations of the reflection coefficients have been developed [1–3] in case of two elastic solids. The possibility of waves propagating along the interface was shown by Pilant [4] and experimentally pointed out [5,6]. The objective of this work is to measure the reflectivity at the interface between two bonded solid half-spaces, of longitudinal and transversal incident waves by taking into account the conversion of modes at the interface. The agreement with theory is good forS 11 and S hh coefficients. In case of an incident vertical transverse waves the reported measurements show some non-specular effect in the angular profile, which, by analogy with what is observed in case of liquid-solid interface, could be interpreted as the existence of a generalized leaky interface wave.
