A two-dimensional chiral structure with an h-shape and H-shape on opposing sides of a dielectric layer is proposed that can realize simultaneously dual-band asymmetric transmission of linearly and circularly polarized waves in the near-infrared band. Meanwhile, the structure realizes a maximum asymmetric transmission of 0.56 and 0.30 for linearly and circularly polarized waves, respectively, at the resonant frequency. These results have been analyzed with simulations in detail. The physical mechanism of linearly and circularly polarized wave transmission and conversion based on current distribution and electric fields is also investigated.
