Abstract : The article surveys the essential results obtained concerning acoustic surface waves on curved surfaces, and establishes their relationships with the corresponding plane surface waves. In view of the limited generality of the existing literature, the excitation mechanisms considered here for the generation of such surface waves have mostly been taken as those provided by a plane incident acoustic wave; more general mechanisms are briefly mentioned. A classification of surface and lateral waves on flat surfaces, and with a description of their properties is given. Surface waves generated by sound scattering on surfaces of simple or arbitrary curvature, both penetrable and impenetrable is discussed. Theoretical results are considered mainly, but selected illustrative examples of the recent experiments are given also. (Author)
