左手材料结构变化对微波透射的影响

Influence of Changing Left-handed Material Structure on Microwave Transmission

以金属铜四边形开口谐振环(SRR)与不同形状和尺寸金属铜线的组合为左手材料结构单元,利用HFSS9软件仿真计算了不同结构的一维左手材料对微波透射的影响.结果表明,结构的变化(尺寸或形状改变)使材料的一元周期性发生变化,导致材料的谐振条件和谐振峰的谐振频率、通频带宽及谐振强度随之发生改变.

Combined the split ring resonators （SRR）with the different shapes and the sizes of metal copper wire as the left- handed material structure unit, this paper discusses the influence on the microwave transmission with different structures of one - dimensional left - handed material calculated by the HFSS9 software. The result indicates that the change of structures （ in size or shape） led to a one - dimensional periodical change of structure, and the resonance condition, the resonance frequency of resonant peaks, the resonant intensity and the width of band pass changes as well.
