Double cross-shap e broadband low-loss and small units left-handed metamaterials based design and exp erimental verification

摘要: 提出了一种利用电谐振器与磁谐振器集成于一体的单面左手介质结构设计方案，该方案采用两个十字架型金属结构镜像并列放置在介质基板的同一侧形成一个左手单元，并将其排列成周期结构.软件仿真和优化提取了一系列有效电磁参数，结果表明，该结构在9.4—16 GHz的频率范围内等效介电常数和等效磁导率同时为负，其相对带宽达到了52%，并且单元电长度和损耗都小于同类型的结构.对该结构进行了加工、制作并通过波导法测试再次证明了其优良左手特性的存在性.为左手材料的广泛应用打下了基础.

Abstract: A method of designing a single side left-handed structure based on the integration of electric resonator and magnetic resonator is proposed in this paper. The left-handed units are composed of two cross types of metal mirrors that are parallel-placed on the same side of the substrate and then arranged into a periodic structure. The results of HFSS software simulation and a series of effective electromagnetic parameters extraction show that the left-handed structure exhibits negative effective permittivity and permeability simultaneously in a frequency range from 9.4 GHz to 16 GHz. Its relative passband reaches 52%, and the unit electrical length and loss are less than those of the same type of structures. The periodic structure is fabricated and tested using the waveguide method. The fine left-handed feature is proved again. This new structure lays a foundation for the wide applications of left-handed metamaterials.
