Metamaterials: Bifunctional Spatiotemporal Metasurfaces for Incident Angle‐Tunable and Ultrafast Optically Switchable Electromagnetically Induced Transparency (Small 21/2021)

In article number 2006489, Tian Jiang and co-workers propose bifunctional spatiotemporal terahertz metasurfaces, which perform versatile, ultrafast terahertz switching behaviors at continuously alterable resonant states. The incident-angle tunable EIT/LC resonance can be effectively switched-off by means of photon injection.
