A wave‐based hybrid ray‐mode algorithm has recently been developed to parametrize mid‐ and high‐frequency sound scattering from submerged empty and simply loaded cylindrical shells [Felsen et al., J. Acoust. Soc. Am. 87, 554–569 (1990)]. The present study extends the hybrid ray‐mode scheme to acoustic scattering from a submerged infinite cylindrical elastic shell with annular ribs attached internally at periodic intervals. Assuming thin shell dynamics, the problem is solved by adapting to the nonperiodic azimuthally unbounded domain (−∞ |
