摘　　要：Transmissive metasurfaces are essentially conducive to stealth,absorbers,and communications.However,most of the current schemes only allow microwave to transmit and generally adopt multilayer structures or thick dielectric substrates to improve the electromagnetic performance,restricting optical transmission and conformal application.In addition,most metasurfaces still require metal wires and external power suppliers for programmability.Here,we propose and design an intelligent transmissive microwave metasurface with optical sensing and transparency,which provides both microwave and optical channels without redundant optical devices and power suppliers,and the 2 transmission channels are associated with each other.The metasurface is realized by validly integrating photosensitive materials into microwave meta-structures.As a demonstration,we fabricate an ultrathin optically transparent transmissive metasurface based on polyethylene terephthalate substrate and photoresistors,whose thickness is only 0.125 mm.We further construct cross-wavelength transmission links based on the metasurface sample and experimentally validate that the microwave transmissions vary with light intensities under full-polarization and large-angle incidences,and this metasurface possesses high optical transparency.The intelligent transmissive microwave metasurface with optical sensing and transparency has potential applications in optical–microwave hybrid transmission devices and stealth technology.
