摘要
传输线结构的Metamaterial的平衡点在研究其传输性质时具有重要的意义。文中对传输线结构的一维Metamaterial进行了电路仿真并从理论上讨论了Metamaterial平衡点的物理意义。当负介电常数的终止频率与负磁导率的终止频率一致时,禁带消失。从另一角度来看,当微带传输线的波阻抗与加载电容和加载电感所组成的负折射系统的波阻抗相同时,电路平衡。
The balance point of one dimension periodic structure is very important in the transmission line metamaterial. When the end frequency of the negative permittivity equals that of the negative permeability, the bandgap disapperars. From other view when the wave resistance equals that of the negative system which consists of loaded capacitance and loaded inductance, the balance state is reached.
