Water waves in natural environments are typically broadband, nonlinear, and dynamic phenomena. Taking concepts developed for slow light in optics, we address the challenge of designing arrays to control the spatial distribution of wave energy, and amplify specific frequencies from within target frequency bands at individual locations. Meter-scale wave-flume experiments, in which incident waves interact with a chirped array of eight vertical cylinders, demonstrate significant amplifications over a broad frequency range, as predicted numerically and theoretically.

chi阵列中水波能量放大的宽带控制实验实现

自然环境中的水波通常是宽带，非线性和动态现象。采取针对光学中的慢光而开发的概念，我们解决了设计阵列以控制波能的空间分布并在各个位置的目标频段内放大特定频率的挑战。米级的波槽实验，其中入射波与八个垂直圆柱体的array阵列相互作用，证明了在很宽的频率范围内的显着放大，这在数值和理论上都是预测的。
