摘要
In this paper, a chiral metamaterial that consists of two complementary U-shaped structures on both sides of a substrate is proposed, which achieves dual-band asymmetric transmission effect of linearly polarized wave at 0.88 and 1.03 THz bands. The asymmetric transmission effect and resonance frequency can be adjusted through changing structure parameters. The physical mechanisms of dual-band asymmetric transmission are also analyzed based on different couple modes excited at resonant frequency.
