论文摘要
一个基于3D印刷金属光子晶体的Terahertz（THZ）波导在0.1-0.6 THz中在实验和数值上被证明，该晶体由周期性金属杆阵列（MRAS）组成。结果表明，这种波导支持了两种波导模式，例如基本和高阶TM模式。高阶TM模式显示高场限制，并且对几何变化敏感。通过调整金属杆间空间，可以优化高频带的光谱位置，带宽和透射率。调查表明，当通过更改空间空间破坏MRAS对称性时，高阶模式之间的模式转换发生。
One terahertz (THz) waveguide based on 3D printed metallic photonic crystals is experimentally and numerically demonstrated in 0.1-0.6 THz, which consists of periodic metal rod arrays (MRAs). Results demonstrated that such waveguide supports two waveguide modes such as fundamental and high-order TM-modes. The high-order TM-mode shows high field confinement, and it is sensitive to the geometry changes. By tuning the metal rod interspace, the spectral positions, bandwidths, and transmittances of the high-frequency band can be optimized. The investigation shows that a mode conversion between high-order modes occurs when the MRAs symmetry is broken via change the air interspace.
