Abstract
The scattering of an acoustic wave from an absorbing half-plane couple d with an elastic half-plane is considered. The planes are subjected t o heavy-fluid loading where the coupling between the fluid and the pla te motions is significant. It is observed that the scattered field con sists of a subsonic surface wave (Biot-Stoneley wave) traveling along the elastic plate and an edge diffracted wave. The effect of absorptio n on the scattered field is shown explicitly in terms of the absorbing parameter.
