Abstract

In this paper, a multi-layered terahertz metamaterial has been proposed, which consisted of dual-layered substrate and three 6-shaped meta-layered. Numerical results reveal that the structure realizes broadband asymmetric transmission of linearly polarized wave. In particular, this structure realizes a maximum of 0.95 for asymmetric transmission at 6.7THz. Based on the electric fields, we have analyzed the wave conversion of linearly polarized wave and the mechanism of asymmetric transmission effect.
