摘要
左手材料通过其特殊的结构阵列来实现负的介电常数和磁导率,将之应用到天线罩、滤波器和天线等方面,可以较好地改善特性。2种新型左手材料结构被提出,分别是史密斯方形环的简化形式和P型结构,其中P型结构又包含基本形式与改进形式。针对这2种模型,利用仿真软件进行了仿真设计,发现这2种形式可以在4～6 GHz频段实现负的介电常数和磁导率,其中P型结构实现效果更好。
Left-handed materials can realize negative dielectric constant and magnetic permeability by special structure array, which can improve characteristics of radome, filter and antenna, etc. Two new left-handed material structures are proposed, which are simplified form of Smith Square Rings and the P-type structure,while the P-type structure contains basic form and modified form. The result of software simulation of these two models shows that dielectric constant and magnetic permeability can be realized from 4 GHz to 6 GHz,and the result of P-type structure is better.
