Enhancement of Optical Chirality Using Metasurfaces for Enantiomer-Selective Molecular Sensing

Applied Sciences, 2021
Circular dichroism (CD) is a physical property observed in chiral molecules by inducing the difference of absorption between left- and right-handed circularly polarized light (CPL). Circular dichroism spectroscopy is widely used in the field of chemistry

Measuring circular phase-dichroism of chiral metasurface

Nanophotonics, 2019
The ability of chiral media to differentiate circularly polarized light is conventionally characterized by circular dichroism (CD) which is based on the difference in the absorption of the incident light for different polarizations.
