We discovered that a one-dimensional groove array can mimic negative water depth and generate unidirectional surface polaritons for water waves. Through theoretical analysis, numerical simulations, and experiments, we explained this phenomenon, demonstrating that the propagation direction of water waves can be controlled using such simple structures. This has significant implications for offshore transportation and environmental protection.
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.
