Abstract
In this work, we provide experimental evidence of negative refraction using a locally resonant metamaterial with hyperbolic dispersion, supported by a theoretical model. By characterizing both elliptical and hyperbolic regimes, our results demonstrate the potential of metamaterials in controlling water waves, opening up new possibilities in wave manipulation technologies.
