Abstract: Circular polarizers based on the metasurface suffer from the trade-off between the structural complexity and the polarization extinction ratio. Herein, we present a single-layer chiral metasurface with strong circular dichroism. The structure turns a circularly polarized incident beam into a linearly polarized one, achieving a high circular polarization extinction ratio. The operating wavelength of the proposed metasurface is tunable by changing the geometric parameters. Localized surface plasmon resonances between structures guarantee strong chiral optical effects of the metasurface. We further experimentally demonstrated the circular dichroism of the fabricated metasurface.
