HIGHLIGHTS
- who: Nanophotonics and colleagues from the Terahertz and Millimeter Wave, City University of Hong Kong, Hong Kong, Hong Kong, China have published the research work: Superheterodyne-inspired waveguide-integrated metasurfaces for flexible free-space light manipulation, in the Journal: (JOURNAL)
- what: Inspired by the superheterodyne principle in radio communications here the authors propose a new waveguide-integrated metasurface architecture capable of converting in-plane guided modes into any desired out-of-plane free-space modes. A theoretical model verified by simulation and experiment is developed to provide a deep understanding of the involved physical mechanism . . .
