A Metasurface Superstrate for Mutual Coupling Reduction of Large Antenna Arrays
IEEE Access, 2020 In this paper, a ε-negative metasurface superstrate is proposed for mutual coupling reduction of large antenna arrays. Unlike the previous decoupling metasurface works that are mostly confined to two-ports antennas, the proposed decoupling ...

Coherent control of Snell's law at metasurfaces [PDF]
, 2014 It was recently demonstrated that the well-known Snell's law must be corrected for phase gradient metasurfaces to account for their spatially varying phase, leading to normal and anomalous transmission and reflection of light on such metasurfaces.
