Periodic nanostructures in photonics facilitate a far-reaching control of light propagation and
light–matter interaction. This article reviews the current status of this subject, including both …

Optical skyrmions have recently been constructed by tailoring vectorial near-field
distributions through the interference of multiple surface plasmon polaritons, offering …

We propose, fabricate, and study a double-layer chiral planar metamaterial that exhibits
pronounced circular dichroism at near-infrared wavelengths. The antisymmetric oscillation …

We show that in the visible to near-IR part of the spectrum, normal incidence transmission of
circularly polarized light through a nanostructured anisotropic planar chiral metamaterial is …

Circular dichroism (CD) effects have broad applications in fields including biophysical
analysis, analytical chemistry, nanoscale imaging, and nanosensor design. Herein, a novel …

Using a modal matching theory, we demonstrate the generation of short-range, chiral
electromagnetic fields via the excitation of arrays of staggered nanoslits that are chiral in two …

A novel route of superchiral near-field generation is demonstrated based on geometrically
achiral systems supporting degenerate and spatially superimposed plasmonic modes. Such …

Chirality is an intriguing property of certain molecules, materials or artificial nanostructures,
which allows them to interact with the spin angular momentum of the impinging light field …

Light interacts differently with left and right handed three dimensional chiral objects, like
helices, and this leads to the phenomenon known as optical activity. Here, by applying a …

We employ a homogenization technique based on the Lorentz electronic theory to show that
planar chiral structures (PCSs) can be described by an effective dielectric tensor similar to …
