中文摘要：

提出了基于金属结构单元间耦合进行左手材料设计的思想,并建立了理论分析模型.通过合理选择结构单元的结构参数并通过单元之间的耦合,使电谐振等效电路的谐振频率与磁谐振等效电路的谐振频率相等,从而最大限度地实现宽左手频带.加工、制作并测试了基于金属结构单元间耦合的左手材料.实验结果表明,测试样品具有相等的电谐振频率和磁谐振频率,其左手频带的带宽为2.4GHz.实验结果与理论分析一致,验证了基于金属结构单元间耦合的左手材料设计思想.

英文摘要：

A method of designing left-handed metamaterials based on inter-unit-cell coupling was proposed in this paper. A theoretical model was established using equivalent circuit theory. By properly setting the geometrical parameters of adjacent unit cells,the electric resonance frequency can be made equal to the magnetic resonance frequency. Thus,the left-handed bandwidth reaches its maximum. A typical left-handed metamaterial based on inter-unit-cell coupling was fabricated and tested. The experimental results show that the test sample has equal electric and magnetic resonance frequencies and the left-handed bandwidth is 2. 4 GHz. This verifies the design method proposed in this paper.
