| 英文摘要 | In this paper, one kind of helix-like chiral metamaterial which can be realized by multiple conventional lithography or electron beam lithographic techniques is proposed to have a broadband bianisotropic optical response analogous to helical metamaterials. on the basis of twisted metamaterials, via tailoring the relative orientation within the lattice, the anisotropy of arcs is converted into magneto-electric coupling of closely spaced arc pairs, which leads to a broad bianisotropic optical response. by connecting the adjacent upper and lower arcs, the coupling of metasurface pairs is transformed into the coupling of the three-dimensional inclusions, and provides a much broader and higher bianisotropic optical response. for only a four-layer helix-like metamaterial, the maximum extinction ratio can reach 19.7. the operation band is in the wavelength range of 4.69 mu m to 8.98 mu m with an average extinction ratio of 6.9. and the transmittance for selective polarization is above 0.8 in the entire operation band. such a structure is a promising candidate for integratable and scalable broadband circular polarizers, especially it has great potential to act as a broadband circular micropolarizer in the field of the full-stokes division of focal plane polarimeters. |
