Tunable Graphene Metasurface Reflectarray for Cloaking, Illusion and Focusing
Sudipta Romen Biswas, Cristian E Gutiérrez, Andrei Nemilentsau +4
We present a graphene-based metasurface that can be actively tuned between different regimes of operation, such as anomalous beam steering and focusing, cloaking and illusion optic…
