The helical Rayleigh wave propagating on the surface of an elastic cylinder immersed in water is theoretically and experimentaly studied. The experimental detection of this wave is carried out following two different ways. In the first, the position of transducers is defined by the Snell-Descartes laws, and the wave is detected thanks to destructive interferences with the specularly reflected wave. In the second, transducers are separated with regard to the previous position, and the propagation of the wave is detected from maxima of pressure measurement at resonance frequencies.
