Abstract: The present invention relates to a system and device (1000) for controlling hydroelastic surface waves and to the use thereof. In particular, the invention relates to a system for controlling hydroelastic waves propagating over the surface of a liquid (1), the controlling system comprising a floating composite structure (10) having at least two zones Z1 and Z2 the respective bending coefficients D1 and D2 and/or the shapes of which are adapted to control the propagation of the hydroelastic waves, and for which it is possible to define an index ni, i being equal to 1 or 2, similar to the refractive index of an optical medium. The controlling system thus allows the propagation of the hydroelastic waves to be able to be controlled by applying the laws of geometric optics.
