摘　　要：We experimentally investigate the reflection behaviors of negative permeability metamaterials （NPMs） consisting of a periodic array of copper hexagonal split ring resonators （SRRs）. Results show that, for the two-dimensional （2-D） NPMs samples, a reflectivity peak with the height of 10 dB appears near the resonance frequency, and the reflectivity is remarkably weak on both sides of the transmission gap; the reflection behaviors of 3-D samples similar to that of the 2-D ones are strongly affected by the lattice constants; the reflection phase increases with the frequency, and an inflexion exists at the resonance frequency of 2-D samples.我们试验性地调查由铜的一个周期的数组组成的否定渗透元材料(NPM ) 的思考行为六角形的裂口戒指共鸣器(SRR ) 。结果显示出那，为二维(2-D ) NPM 取样，有 10 dB 的高度的一座反射率山峰在回声频率附近出现，并且反射率在传播差距的双方上是显著地弱的；类似于 2-D 的 3-D 样品的思考行为被格子常数强烈影响；思考阶段与频率增加，并且一个屈折变化在 2-D 样品的回声频率存在。
