The chiroptical properties of metasurfaces are promising research field due to its potential applicability for flat optics. However, obtaining tunable optical properties is still challenging. Herein, we fabricated the chiral surface pattern by using a Polydimethylsiloxane (PDMS) transferred from the grating with gold sputtering (au-gPDMS). The Au-gPDMS has circular dichroism (CD) spectrum according to surface asymmetry, curvature, and direction of curvature. As a result, it was confirmed that curvature had the greatest effect on chirality. These results will open the novel method to approach tunable metasurfaces.
