提出了一种新型部分负曲率反谐振空芯太赫兹波导,波导包层包括两部分,一部分由介质圆管组成,为纤芯提供部分负曲率边界;另一部分由多个矩形介质层组成,多介质层可用来降低限制损耗.此波导结构在增加反谐振层的同时不引入新的包层节点,易于实现太赫兹波的宽带低损耗传输.采用全矢量有限元法对波导进行了数值仿真,研究了其宽带低损耗特性.基于此,利用3D打印技术制备了所设计波导,使用太赫兹时域光谱系统对其传输特性进行测试.实验结果表明,该负曲率太赫兹波导在0.29~ 0.42THz的传输损耗低于10 dB/m,与数值仿真结果吻合较好. |

A novel partial negative curvature anti-resonance hollow-core terahertz waveguide is proposed. The waveguide cladding consists of two parts,one part is composed of a dielectric circular tube,which provides a part of the negative curvature boundary for the core;the other part is composed of a plurality of rectangular dielectric layers,and multiple dielectric layers for reducing confinement loss.This waveguide structure does not introduce a new cladding node while adding anti-resonant layers,and it is easy to achieve broadband low-loss transmission of terahertz waves.The full vector finite element method is used for the numerical simulation of the waveguide,and the broadband low loss characteristic is investigated.Based on the simulation analysis,the designed waveguide is printed via 3D printing technology,and the transmission characteristics are tested using a terahertz time-domain spectroscopy system.Experimental results show that the transmission loss of this negative curvature anti-resonance terahertz waveguide is less than 10 dB/m in the range of 0.29~0.42THz,which is in good agreement with the numerical simulation. |
