Boat wake incidence on a microstructured wall

We conducted experiments investigating the interaction between a boat wake and a subwavelength microstructured wall. In our study, we consider a ship that moves at a constant speed parallel to the wall. We investigated the reflection resulting from the interaction of the ship's wake with the wall. By modifying the geometry of the microstructure to couple its resonant frequency with the wavelength of the ship's wake, we were able to achieve total absorption. Our findings illustrate the successful manipulation of water waves by the use of subwavelength resonances, resulting in the efficient absorption of the incident waves. This study sheds light on the potential for utilizing microstructured surfaces as a means to control and mitigate the impact of ship wakes on surrounding structures.
