摘      要：Intelligence at either the material or metamaterial level is a goal that researchers have been *** passive to active,metasurfaces have been developed to be programmable to dynamically and arbitrarily manipulate electromagnetic(EM)***,the programmable metasurfaces require manual control to switch among different ***,we put forth a smart metasurface that has self-adaptively reprogrammable functionalities without human *** smart metasurface is capable of sensing ambient environments by integrating an additional sensor(s)and can adaptively adjust its EM operational functionality through an unmanned sensing feedback *** an illustrative example,we experimentally develop a motion-sensitive smart metasurface integrated with a three-axis gyroscope,which can adjust self-adaptively the EM radiation beams via different rotations of the *** develop an online feedback algorithm as the control software to make the smart metasurface achieve single-beam and multibeam steering and other dynamic reactions *** proposed metasurface is extendable to other physical sensors to detect the humidity,temperature,illuminating light,and so *** strategy will open up a new avenue for future unmanned devices that are consistent with the ambient environment.
