キーワード:Circularly polarized light, circular dichroism, metasurface

A chiral plasmonic absorber using lightning-shaped nanostructures was demonstrated to achieve spectrally selective chiral in the visible region. The absorption can reach up to 84% for RCP and the circular dichroism (CD) is ~30% at the wavelength of 640 nm.
