中文摘要：

通过左右手复合传输线（CRLHTLs）实现了一维的特异材料（Metamaterials），基于Metamaterials单元构成了光子晶体，并分析、测试了其传输特性．实验结果表明，由特异材料构成的一维光子晶体具有Bragg带隙和等效的单负带隙．当晶格尺度同比例改变时，等效的单负带隙基本上不发生移动，并且带边分别由零平均介电常数ε=0和零平均磁导率μ=0决定．零平均折射率（zero-n）带隙和零有效相位（zero-φeff）带隙可以理解为一种等效的单负带隙．对由Metamaterials构成的一维光子晶体传输特性的研究，有助于Metamaterials在射频／微波电路和仪器中的应用．

英文摘要：

One-dimensional metamaterials were realized by using composite right/left-handed transmission lines （CRLH TLs） , the transmission properties of the photonic crystals composed of metamaterials based on microstrlps lines were measured and analyzed. The experimental results indicate that the photonic crystals possess Bragg gaps and effective-single-negative （ESNG） gap, and the ESNG gap does not shift when the lattice constant varies by the same factor, and the edges of the gap are determined by zero average permittivity ε=0 and zero average permeabilityμ = 0, respectively. Zero-n gap and zero-φeff gap can be understood as an ESNG gap. The investigations of the photonic crystals consisting of metamaterials will benefit to the applications of the metamaterials in RF/microwave circuits and apparatus.
