摘　　要：根据周期性放置的金属线和SRRs(开口金属环共振器)结构单元的模型,讨论了这2种结构单元的介电系数ε和磁导率μ的取值,从理论上定性分析了如何控制这2种结构单元的尺寸参数,实现不同频率下的超材料.最后,根据ε和μ的符号,把材料分为4类,并分别讨论了这4类材料的反射和透射性能以及目前主要的研究领域.In this work, artificial composite structures consisting of periodically placed parallel metallic wires and spilt ring resonators are presented. Based on these two models, and the value of the electric permittivity ε and the magnetic permeability μ, separately is discussed. By controlling the size of these two units, metamaterials for different frequencies can be obtained. At last, according to the sign of ε and μ, the reflection and transmission of materials are discussed.
