共面负折射指数波导的电容缺陷对传输特性的影响

Effect of Defect Capacitance in Coplanar Waveguide Metamaterials on Transmission Properties

在实际负折射指数漏波天线加工中经常出现误差,文章研究了负折射指数漏波天线的电容缺陷对传输特性的影响。利用缺陷负折射指数理论,得出当电容缺陷刚引入时,传输特性变化极其明显,而电容缺陷变大时,传输特性变化将很小,因为间距的变化破坏了负折射指数漏波天线整体对称性。

There are some defects in practical Coplanar Waveguide metamaterial＇s fabrication. Effect of defeet introduced into capacitance of Coplanar Waveguide metamaterials on transmission properties is investigated. Using the theory of defect Coplanar Waveguide metamaterials, the results show that there exists a sharp shift for transmission properties deduced by the introduction of defect capacitance into Coplanar Waveguide metamaterials, the increasing defect capacitance affects transmission properties little, because the changed gap break Coplanar Waveguide metamaterial＇s symmetry.
