Graphene-assisted metagrating: from coherent to angular-asymmetric control of absorption and reflection
Ensiye Ghorbanpour, Sahar Behroozinia, Ali Abdolali
In this paper, we exploit the metagrating paradigm to achieve coherent control of absorption and reflection in a two-port device. Employing graphene ribbon as a tunable element all…

Real-time Terahertz Wave Channeling via Multifunctional Metagratings: A Sparse Array of All-Graphene Scatterers
Sahar Behroozinia, Hamid Rajabalipanah, Ali Abdolali
Acquiring full control over a large number of diffraction orders can be strongly attractive in the case of realizing multifunctional devices such as multichannel reflectors. Recent…
