Abstract
The effects of an almost-periodically spaced set of ribs on the scattering of sound from a submerged cylinder of finite length are investigated. The cylinder is either assumed soft (corresponding to a very thin air-filled shell), or rigid (corresponding to a heavy thick shell) and its scattering amplitude is obtained using the geometrical theory of diffraction. The rib scattering amplitude is found from curvature-corrected results of the theory for a flat plate carrying a rib. Numerical results were obtained for the case of soft cylinders (i.e., thin, air-filled shells); they exhibit the onset and emergence of rib effects over the background of scattering from the body of the cylinder.
