Realization of Index Modulation with Intelligent Spatiotemporal Metasurfaces

Advanced wireless communication with high spectrum efficiency and energy has always fascinated humanity, especially the explosive increase of global mobile data services. Index modulation (IM) recently been found to be a promising technique due transmission additional bits via indices available transmit entities. However, practical implementation IM remains great challenge associated complicated radio components. Herein, intelligent spatiotemporal metasurfaces is experimentally demonstrated. The provide natural versatile platform achieve in green lightweight manner. whole system driven by built-in inverse-design agent that automates cater diverse application demands. In doing so, how mitigate inherent nonuniqueness issue setup input target from scenes are concretely discussed. microwave experiment, fabricated demonstrate feasibility harvesting two harmonic waves as channels. An electromagnetic can manipulate multidimensions provided, meriting other numerous meta-devices avoid overburdening analysis networks smart cities future.
