摘　　要：为拓宽异向介质结构的带宽和维数,在方形环结构的基础上,提出了一种异向介质的交叉网状结构的设计,并对其介电常数和磁导率的频率特性进行了计算机仿真。研究结果表明,该结构在特定的频段内表现出了明显的负折射特性,与传统的裂环谐振器相比,新结构的结构对称、具有更宽的响应带宽和三维各向异性等特点。In order to increase the negative refraction bandwidth and the dimension of metamaterials, based on a quadrate structure, a crossing-net metamaterial structure is proposed, and the frequency properties of its permittivity and permeability are simulated. The results indicate that the new structure has negative refraction index in a certain bandwidth. Compared with the original SRRs-wires structure, the new structure has the advantages of symmetric structure, wider response bandwidth and three-dimension anisotropism properties.
