(a) Form A of the slanted split-ring aperture (left) with the SEM image (right) and the CDT (circular dichroism in transmission) spectra for both forms (center). (b) Form B of the slanted split-ring aperture (left), the SEM image (right) and the reflection and absorption spectra for Form A under LCP and RCP incidence light (center). (c) A L-shaped aperture metasurface (left), the SEM image (right) and the CDT from experiments and simulation (center).
