A bstract In continuation of our earlier work on interface waves (Gupta and Martel 1971) we have extended our studies by using a plexiglas‐steel combination in addition to plexiglas‐brass. Two other emitter positions were also considered: emitter on plexiglas and emitter on the metal edge, a short distance away from the interface. In both cases the presence of an interface wave could be detected from the seismogram. A curved interface between plexiglas and brass was also studied and it was found that the curvature introduces a change in the phase velocity of the interface wave in the same way as a curved surface does for the Rayleigh wave.
