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.
我们发现一维凹槽阵列可等效于负水深，并能激发水波的单向表面极化激元。我们通过理论分析、数值模拟和实验来解释这一现象。该现象表明，通过这种简单结构可以操控水波的传播方向，这在海上运输和环境保护方面将非常重要。
