Abstract : This study is concerned with surface waves which propagate along an interface between a fluid and an elastic solid. In particular, interesting transmission and radiation behavior is caused by a wedge-shaped discontinuity in the interface. An iteration procedure is employed by which the boundary conditions on either face of the wedge are alternately satisfy. Using only the first iteration produces a transmission coefficient. Numerical data is presneted showing the manner in which the transmission coefficient depends upon the angle of the discontinuity. Results are compared with those of related studies appearing in the recent literature. (Author)
