本文从实验和理论两方面研究了劈裂环谐振器（SRR）型超材料元件之间的耦合机理。我们表明，根据元素相对于彼此的方向，耦合可以是磁性或电型的，也可以是两者的组合。共振频率在1.7 ~ 1.9 GHz的SRRs的实验结果与CST Microwave Studio的模拟结果在定量上一致。进一步的仿真提供了在GHz和20thz频率区域的各种srr的分析。多种耦合机制可用于设计基于慢波传播的近场操纵装置。2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim。
We study experimentally and theoretically coupling mechanisms between metamaterial elements of the split ring resonator (SRR) type. We show that, depending on the orientation of the elements relative to each other, the coupling may be either of magnetic or electric type or a combination of both. Experimental results on SRRs with resonances around 1.7-1.9 GHz agree quantitatively with results of simulations (CST Microwave Studio). Further simulations provide analysis for a variety of SRRs both in the GHz and in the 20 THz frequency regions. The variety of coupling mechanisms can be employed in designing near field manipulating devices based on propagation of slow waves. C 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
