Dielectric Resonator Metasurface for Dispersion Engineering
, 2016 We introduce a practical dielectric metasurface design for microwave frequencies. The metasurface is made of an array of dielectric resonators held together by dielectric connections thus avoiding the need of a mechanical support in the form of a ...

Dielectric Meta-Atoms with Liquid Crystal Alignment Effect for Electrically Tunable Metasurface
Advanced Devices & InstrumentationDielectric metasurfaces with tunable functions are increasingly appealing to both the academia and industrial communities. Among the many tuning mechanisms reported so far, metasurface immersed in liquid crystal (LC) stands out as one of the most viable ...

Singular graphene metasurfaces [PDF]
EPJ Applied Metamaterials, 2019 The spatial tunability of the electron density in graphene enables the dynamic engineering of metasurfaces in the form of conductivity gratings, which can bridge the momentum gap between incident radiation and surface plasmons. Here, we discuss singular graphene metasurfaces, whose conductivity is strongly suppressed at the grating valleys.

Advanced Functional Materials, EarlyView.A chiral photodetector capable of selectively distinguishing left‐ and right‐handed circularly polarized light is experimentally demonstrated. The device, which features a nanopatterned electrode inverse‐designed by a genetic algorithm within a metal–dielectric–metal nanocavity that incorporates a vacuum‐deposited small‐molecule multilayer, exhibits ...

Coherent optical control of polarization with a critical metasurface
, 2015 We describe the mechanism by which a metamaterial surface can act as an ideal phase-controlled rotatable linear polarizer. With equal-power linearly polarized beams incident on each side of the surface, varying the relative phase rotates the polarization
