摘要:
提出一种由金属开口环阵列结构构成的太赫兹各向异性超材料，通过有限元数值仿真，以及太赫兹透射光谱测试，对该结构在太赫兹波段的各向异性特征进行分析，证明了其因开口环结构的各向异性和产生太赫兹透射调制的各向异性．最后对该各向异性超材料的太赫兹偏振转换特性进行实验测试，获得与常规光学双折射材料规律一致的偏振转换结果．该人工结构材料有望应用于太赫兹玻片及隔离器等．
Abstract:
A terahertz anisotropic metamaterial based on metal slit ring array is proposed and discussed. The anisotropic characteristics of the structure are simulated by the finite element method and measured by terahertz transmission spectroscopy. The anisotropy of the structure due to the anisotropy of metal slit ring array and the developed anisotropic modulation of the terahertz transmission is proved. Finally, the terahertz polarization conversion characteristic of the anisotropic metamaterial is tested experimentally. And the polarization conversion results are obtained by converting the incident wave with linear deviation into its vertical polarization direction, which are consistent with the law of conventional optical birefringent materials. This kind of metamaterial is expected to be used in terahertz wave plates and isolators.
