Abstract
An ultra-thin water metamaterial in the shape of a fishnet structure is designed and analyzed. It is theoretically shown that coherent perfect absorption can be achieved in such a metamaterial, where the reflection and transmission coefficients have same amplitudes and nearly 180° phase delay. Moreover, the coherent absorptivity of the water metamaterial can be manipulated from 0.59% to 99.99% by phase modulation.
