Abstract

We find that a one-dimensional groove array can be equivalent to a negative water depth and excite unidirectional surface polaritons for water waves. We explain this phenomenon through theoretical analysis, numerical simulations, and experiments. This phenomenon shows that the propagation direction of water waves can be manipulated through such simple structures, which will be very important in offshore transportation and environmental protection.

Metamaterials Control the Shape of Water Waves

Published 16 May 2022

A water wave incident on a grooved wall is shown to be analogous to electromagnetic waves called surface plasmon polaritons.
