Over the past 40 years the problem of nonspecular reflection of bounded beams from fluid-solid interfaces has been extensively studied. Early investigations by Schoch [1] and Bertoni and Tamir [2] have concentrated on planar structures, both halfspaces and plates. More recent studies on reflection of sound from cylinders have concentrated on far-field scattering with emphasis on azimuthal resonance phenomena [3, 4], and on specular interaction of well-collimated beams with fluid-solid cylindrical interfaces [5, 6].
