Temperature-controlled reflection and transmission properties in anisotropic terahertz metamaterials
The temperature-controlled unidirectional reflectionlessness and asymmetric transmission in terahertz frequency region are investigated by a double-layer H-type resonator.The results show that when the upper and lower layers of the anisotropic structure are staggered at a certain angle,the asymmetric transmission,asymmetric reflection and unidirectional reflectionlessness of linearly polarized wave can be realized,respectively.Meanwhilethe scheme can also realize the asymmetric reflection and polarization conversion of circularly polarized waves,and can realize the unidirectional reflectionlessness,asymmetric transmission and asymmetric reflection for the linearly polarized and circularly polarized incident waves by adjusting the vanadium dioxide conductivity with temperature change.The scheme provides a reference for the research and design of sensors and filters.
