Modulation of water surface waves with a coiling-up-space metasurface

Blog Article

We have designed a gradient-index Sweater (GRIN) metasurface to modulate water surface waves (WSWs).The metasurface is composed of an array of coiling-up-space units with a deep sub-wavelength scale, and can focus/scatter WSWs when the units are arranged elaborately and pierced into water.The modulation of WSWs has been ascribed to the relative effective refractive GRIN of the coiling-up-space units, which can be tuned by changing the parameters such as the plate length of units.
