摘要
提出了一种蘑菇型磁谐振环结构,并结合金属丝电谐振结构设计了左手材料单元。利用CST电磁仿真软件,通过平面波入射实验、等效电磁参数提取及波导仿真实验等方法验证了左手通带的存在。这种磁谐振环结构由单匝开口环路串连而成,相比于传统的多环路开口谐振环有着更为简单的结构形式,便于材料的加工和制备。同时,这种前后相邻的磁谐振环固有的金属条结构,也为左手材料的电磁谐振提供了一种电容耦合单元。
A new mushroom magnetic resonance structure is presented,while and the left-handed metamaterial is designed based on this structure and the metal strip structure.With the help of electromagnetic simulation software CST,the left-handed pass band is verified by the simulation of electromagnetic wave transmission,extraction of equivalent electromagnetic parameters and experiment of wave-guide simulation method etc.This magnetic resonance structure is composed of a series of simplex split loops,which has a simple structure compared with the traditional multi-loop split resonance structure,and it is convenient to be used for fabricating left-handed metamaterials.Meanwhile,the neighbor metal strips of every two magnetic structures arranged front and rear also provide a coupling capacitance to the electromagnetic resonance of left-handed metamaterials.
