【摘要】 本文提出了双频带三环开口谐振(threesplit-ringresonator,TSRR)结构,与金属线进行组合可构成双频带左手超材料。通过有限积分技术(finite integral technology,FIT)进行的基本单元结构仿真和理论分析表明,单个TSRR结构在X波段能够实现双频带负磁特性,与共面双金属线(doublemetalwires,DMW)进行适当的组合能够同时实现双频带"双负"特性(负介电常数和负磁导率)。该TSRR结构简单、制备方便,可用于双通带滤波器、耦合器等微波器件的设计制作。更多还原

【Abstract】 In this paper,a three split-ring resonator(TSRR)is proposed,which combine with the coplanar double metal wires can be made of dual-bands left-handed metamaterials. The unit cell of TSRR could achieve dual-bands negative permeability by simulating of unit cell structure of fi nite integration technology(FIT)and theorical analyse. The TSRR combine with the double metal wires(DMW)properly which could achieve dual-bands "double-negative" simultaneously(negative permittivity and negative permeability). This structure of TSRR is very simple,and easy to be fabricated,moreover,which could be used to design and fabricate of dual-bands filters,couplers and other microwave devices.更多还原
