(a) Schematic view of a coiling-up-space structure with a layer of thin pedestal placed in water. The height h 1 is 2.5 m and the water depth h 0 is 2 m. (b) Top view of the structure. The length of rigid plate is expressed as l , and n denotes the number of the curled channels. (c) The phase shift of a metamaterial versus plate length l and channel number n .
