我们提出了一种在一定频率范围内具有左手性质的二维超材料，其中有效介电常数和磁导率同时为负。采用楔形超材料结构进行折射率测量。在左手频率范围内，该结构具有负折射率。测量连续多层超材料结构之间的相移，并根据相移量计算负折射率值。结果表明，该结构具有负相速度。由两种独立的不同方法得到的折射率值符合得很好。
We present a two-dimensional metamaterial with left-handed properties in a certain frequency range where both effective dielectric permittivity and magnetic permeability is simultaneously negative. A wedge-shaped metamaterial structure is employed for refractive index measurements. At the left-handed frequency range the structure is shown to have negative refractive index. Phase shift between consecutive number of layers of metamaterial structures are measured and a negative refractive index value is calculated from the amount of the phase shift. The structure is shown to have negative phase velocity. The refractive index values obtained from two different and independent methods are in good agreement.
