摘要
利用现代光刻技术工艺制备了一种圆形和两种分别在x和y方向伸展的椭圆形裂环谐振器,并在太赫兹时域系统进行测试,比较了尺寸结构参数和耦合系数对幅频特性的影响,提出包含LC谐振、偶极子谐振和第3个谐振的改进TL-RLC模型使模型与实验数据更为吻合。并对第3个谐振频率的表达式进行讨论。
Utilizing a series of micro-fabrication processes for terahertz meta materials, we fabricated three geometries of split-ring resonators： a circular geometry and two elliptical geometries. The measured results showed that multiple resonant and the coupling among those resonant had played an important role on the overall response. For better matching TL-RLC model results with measured data, an improved model was introduced. Then the expression of the highest resonant frequencies in the improved model was introduced.
