Abstract
Programmable dynamic metasurfaces enable real-time tailor of electromagnetic waves and acoustic waves, which have aroused a lot of attention. Different from the traditional electrically-controlled programmable metasurfaces, we here present a light-controlled programmable microwave metasurface and its experimental verification. The measured results show that the metasurface sample can be controlled and powered by light intensity patterns for generating dynamic vortex beams with different orders in real time. Such the optically programmable metasurface can simplify effectively the feed network design caused by wired electrical control schemes and enriches the control method of dynamic metasurfaces.
