中文摘要：
磁谐振器与电谐振器组合能够实现同时具有负介电常数和负磁导率的左手材料，左手材料磁谐振器的设计对于设计新型左手材料具有重要的意义。针对左手材料磁谐振器设计问题，提出了磁谐振器设计原理，为消除磁谐振器的双各向异性，所设计的结构关于电场方向等效为镜像对称的单回路。根据此原理，设计了耦合增强型“巨”字形磁谐振器结构，并通过实验仿真验证了结构的等效负磁导率。结果表明，所设计的结构在8．9GHz-10GHz之间具有负的等效磁导率，并且结构的双各项异性得到了有效的消除，说明了所提出设计原理的正确性。相对于传统的开口谐振环磁谐振器，“巨”字形磁谐振器结构简单，易于进行加工制作和理论分析。
英文摘要：
Left- handed meta- materials can be fabricated by combining electric resonators with magnetic resonators to realize simultaneously negative permeability and permittivity, so the design of magnetic resonators is of great importance in designing new types of left - handed meta - materials. Dealing with the design of magnetic resonators, the design principle of magnetic resonators is proposed. The structure of the magnetic resonator must be equivalent to a mirror- symmetrical single loop in order to eliminate the unwanted bi -anisotropy. Based on the design principle, a coupling - enhancement magnetic resonator structure is devised. The negative permeability of the structure is verified by experimental simulations. The results show that the permeability of the structure is negative in 8. 9GHz - 10GHz and that bi - anisotropy is eliminated effectively. Compared with the conventional magnetic resonator SRR, the proposed magnetic resonator is simple in structure and much easier in fabrication and analysis.
