Abstract

We demonstrate the use of a space-time-coding digital metasurface operating in the microwave regime to experimentally generate various modes of time-varying orbital angular momentum (OAM) beams. By developing a time-domain field mapping technique, we are able to observe the generated time-varying OAM. Moreover, we explore an additional higher-order twist in the wavefront structure of time-varying OAM beams based on the flexible programmability of the metasurface. These proposed time-varying OAM beams hold potential for applications in communication and particle manipulation. © 2023, META Conference. All rights reserved.
