摘要 利用微细加工技术,制作出金属矩形孔阵列,从实验和理论上研究了金属矩形孔阵在THz波段的透射极大值和极小值产生的规律.并利用透射极大值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,利用不同尺寸的金属孔结构形成复合金属孔阵列,设计出中心频率可调节、频率拓宽的频率选择器件和频率拓宽器件.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,对太赫兹波技术的发展具有重要意义. An investigation of the mechanism of extraordinary transmission through metal hole array at THz range was presented. The experiments and simulations verified that the metal film perforated with rectangular arrays had a peak which related with the length of the rectangular. Furthermore, by composing rectangular holes with different length to form an array, the transmission spectra exhibit two individual peaks or a broaden peak. This composed array has poten- tial applications in THz filter, polarizer, and reflector.
