Electric field of LCP and superchiral light. (IMAGE)
Caption
(a) Electric field of LCP and superchiral light. (b) (Left) Schematic illustrating the generation of superchiral fields by focusing twisted RP beams. (Right) Theoretical model used to calculate the electromagnetic field distribution near the focal point. (c) (Top) A non-chiral plasmonic system composed of a cavity-coupled aperture array, supporting rotating dipole resonances when excited by CPL. (Bottom) Chirality density in plane waves as they propagate in the negative z-direction, varying with distinct polarization states. (d) (Left) Concept of molar chiral sensing; (right) reflection and CD reflection spectra.
