Broadband Light Bending with Plasmonic Nanoantennas
Xingjie Ni,Naresh Kumar Emani,Alexander V. Kildishev,Alexandra Boltasseva,Vladimir M. Shalaev +4 more
TL;DR: Unparalleled wavefront control in a broadband optical wavelength range from 1.0 to 1.9 micrometers is experimentally demonstrated using an extremely thin plasmonic layer consisting of an optical nanoantenna array that provides subwavelength phase manipulation on light propagating across the interface.

Electrically Tunable Damping of Plasmonic Resonances with Graphene
Naresh Kumar Emani,Ting-Fung Chung,Xingjie Ni,Alexander V. Kildishev,Yong P. Chen,Alexandra Boltasseva +5 more
TL;DR: Electrical control of a plasmonic resonance at infrared frequencies using large-area graphene is demonstrated and full-wave simulations, where graphene is modeled as a 1 nm thick effective medium, show excellent agreement with experimental results.
