摘要:

我们的特点是平面电太赫兹超材料上制作的薄,灵活的基板,使用太赫兹时域光谱。准三维超材料是通过堆叠多个超材料层形成的。透射测量揭示了随着层数的增加而变得更强的谐振带阻行为。提取的超材料介电函数被证明是独立的层数,验证有效介质近似。这种近似的局限性进行了讨论。

英文摘要:

We characterize planar electric terahertz metamaterials fabricated on thin, flexible substrates using terahertz time-domain spectroscopy. Quasi-three-dimensional metamaterials are formed by stacking multiple metamaterial layers. Transmission measurements reveal resonant band-stop behavior that becomes stronger with an increasing number of layers. Extracted metamaterial dielectric functions are shown to be independent of the number of layers, validating the effective medium approximation. Limitations of this approximation are discussed.
