Abstract : The acoustic field of a plane wave incident on an elastic cylinder may be decomposed into two parts, one having the form of circumferential waves propagating around the cylinder, the other one obeying in the high-frequency limit the laws of geometrical optics. For the simpler case of a liquid cylinder, the geometrical part is studied here, and is shown to consist of the specularly reflected wave, and of transmitted waves which traverse the cylinder along a secant, possibly undergoing one or more internal reflections in addition.
