In this paper, we demonstrate an adaptable metasurface with a periodic array of liquid-metal ring-shaped resonators. Its optical properties can be dynamically controlled by individually reconfiguring the geometry (shape and orientation) of the resonators. For the proof of concept, by tailoring the p...
