We aim to realize high circular dichroism in a wide range of visible light by focusing on the difference in absorption when left and right circularly polarized light is incident on a plasmonic metasurface with a chiral structure made of aluminum on a glass substrate. We designed a plasmonic chiral meta surface using simulations using the RCWA method, and were able to find a structure with a CD value of 0.4 in the wavelength range of 400 to 600 nm.
