  • 摘要:

    本文基于对称的类H型结构设计了一种超材料太赫兹带阻滤波器,这种H型结构的连续金属臂可以流通电流,能为拓展超材料滤波器在电子应用领域提供有效参考。利用电磁仿真软件CST Microwave Studio 2021研究了该滤波器的滤波特性,通过改变H型双臂间距臂长、周期长度、双H间距离等,确定了滤波器的几何参数。结果表明,该结构可实现偏振选择的功能,在y偏振条件下,滤波器在0.2~2.3 THz范围内没有明显谐振峰,但透过率范围在−15到−3 dB之间。而在x偏振条件下,可在中心频率1.34 THz处可获得FWHM带宽为0.15 THz的一个阻带,传输参数约为−30 dB。为了验证仿真结果,采用微加工工艺制备了超材料滤波器样品,使用透射式太赫兹时域光谱系统对样品进行测试,测试结果与仿真结果吻合较好。
