Optical metasurfaces with high quality factors (Q-factors) of chiral resonances can boost
substantially light-matter interaction for various applications of chiral response in ultrathin …

Understanding chirality, or handedness, in molecules is important because of the
enantioselectivity that is observed in many biochemical reactions 1, and because of the …

Metamaterials are composed of periodic subwavelength metal/dielectric structures that
resonantly couple to the electric and/or magnetic components of the incident …

We present a comprehensive overview of chirality and its optical manifestation in plasmonic
nanosystems and nanostructures. We discuss top-down fabricated structures that range from …

Metasurfaces that can realize the polarization manipulation of electromagnetic waves on the
