中文摘要：

利用微细加工技术，制作出太赫兹波段人工电磁材料，从实验和理论上研究了金属矩形阵列在太赫兹波段的谐振频率及带宽与矩形长度的关系。并利用谐振频率随矩形孔长度增大而向低频移动的特性，在同一层金属上，将两个不同尺寸的金属矩形结构复合在同一个周期内，制作出单层复合型人工电磁材料。模拟和实验结果表明，单层复合型人工电磁材料实现了调节中心频率、频率拓宽以及多频段带阻功能。此研究为太赫兹滤波器等无源器件提供了新的设计思路和加工方法，对太赫兹科学技术的发展和应用具有重要意义。

英文摘要：

Abstract： The transmission characters of metal strip arrays were investigated at terahertz range. The experiments and simulations verify that the resonance frequency and bandwidth of metal strip are dependent on the length of the rectangular. We proposed a composed single-layer metamaterials assembled by two metal strips with different length. The transmission spectra exhibit multiple band or a broaden band characters. This single-layer metamaterials have a potential application in THz filter, polarizer, reflector fabricated and provides a new method for the THz designing.
