摘要: The invention relates to a double-structure combined type metal nano-film chiral optical structure. structure comprises film,a foundation U-shaped seam located in the film, and reinforcing C-shaped which is positioned parallel arranged one side of seam. According embodiments invention, C-type added film comprising seam, so that current flowing direction original changed, magnetic dipole occurs transverse on basis existence an electric dipole; due action electricdipole dipole, circular dichroism remarkably enhanced.
