摘　　要：用磁谐振器和电谐振器组合构成左手材料是设计左手材料的一个重要方法.基于这一设计方法,提出了能够抑制双各向异性的磁谐振器和电谐振器设计原理,即单回路镜像对称设计原理和双(四)回路镜像对称设计原理.根据这两个设计原理,设计了具有双负特性(负介电常数和负磁导率)的新结构,并通过实验仿真验证了结构的双负特性,从而验证了两种设计原理的正确性.所提出的两个设计原理以及新结构对于设计新型左手材料具有重要的实际意义和指导意义.In designing left-handed metamaterials composed of magnetic resonators and electric resonators,two design principles,that is,the single-loop mirror-symmetry design principle and double-loop（quadruple-loop） mirror-symmetry design principle,were respectively proposed for the design of magnetic resonators and electric resonators.Based on the two principles,new structures with simultaneously negative permeability and permittivity were designed.By means of simulation experiments,the double-negative property of the proposed structure as well as the two design principles was verified.The two design principles and structures proposed in this paper are of great practical values in designing new types of left-handed metamaterials.
