Water waves manipulation using metamaterials and resonant cavities
Water waves represent both an inexhaustible source of energy and a destructive force of considerable magnitude. In both cases, their manipulation and absorption are critical challenges in the current context of global warming. To address these challenges, our team has developed innovative systems inspired by concepts from other wave fields, such as acoustics and optics. These approaches enable more compact and environmentally friendly solutions. For instance, the use of resonant cavities, such as analogous Helmholtz resonators, has proven particularly effective in creating protective barriers against waves or calming rough water surfaces. Additionally, metamaterials offer the possibility of strong wave redirection, which can be used, for example, to protect coastlines. This research was conducted as part of a collaboration between three research laboratories and a start-up, allowing for both fundamental studies on the fine physics of these objects and more application-oriented work to be carried out.
