We propose a liquid-crystal-based reconfigurable chiral metasurface absorber and numerically investigate its chiro-optical properties. The chiral metasurface absorber consists of a metal-insulator-metal structure with the substrate. which can strongly absorb a circularly polarized wave of one spin state and reflects that of the opposite spin. resulting a strong circular dichroism (CD). https://unitedssports.shop/product-category/bike-accessories-saddles/
