Conductivity-driven chirality in geometrically achiral plasmonic nanostructures and metasurfaces
Yulong Duan, Longzhu Liu, Suraya Kazi +7
Resonant nanostructures are powerful for chiral control of light, but widely assumed to require achiral geometry. Here we demonstrate that optical chirality can emerge in geometric…

An electrically tunable metaatom for visible light
Janna Wilhelmsen, Longzhu Liu, Harry Miyosi Silalahi +6
Phase-gradient metasurfaces provide powerful wavefront control through two-dimensional arrangement of nanostructures acting as metaatoms. While dynamic tuning forms a major driver…
