Programmable metasurface for front-back scattering communication. [PDF]
Nanophotonics, 2023 Abstract Achieving high‐efficient and low‐power communication is pivotal yet very challenging in the emerging technologies. Unlike conventional backscatter communication system, we propose and demonstrate an amplitude‐reconfigurable metasurface loaded with PIN diodes to build a front‐back scattering communication transmitter, which ...

Programmable polariton canalization in reconfigurable metasurfaces. [PDF]
Sci AdvThe topological transition of polariton dispersion in twisted van der Waals layers at the photonic magic angle results in the diffraction-less and collimated propagation state, termed canalization regime. This type of robust transport of polaritons (i.e., polariton canalization) holds promise for subwavelength control of energy flows. However, the lack
