N2 - In this study, we experimentally demonstrate the possibility of negative refraction of water waves, using a locally resonant metamaterial. This metamaterial exhibits a dispersion that encompasses elliptical and hyperbolic regimes, characterized by theoretical analysis and supported by experimental validation. In the frequency range associated with hyperbolic dispersion, we confirm and characterize the appearance of negative refraction. Our experimental achievement provides convincing evidence of the potential of metamaterials for water wave control.
