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…

Harnack's inequality for a class of non-divergent equations in the Heisenberg group
Farhan Abedin, Cristian E. Gutiérrez, Giulio Tralli
We prove an invariant Harnack's inequality for operators in non-divergence form structured on Heisenberg vector fields when the coefficient matrix is uniformly positive definite, c…
