| 摘 要： | 本文基于微扰法求得不同金属镀层空心圆波导中各模式的损耗系数,对金属镀层空芯波导中THz波传输损耗随金属材料、波导结构等参数的变化关系进行了数值模拟.根据数值分析结果,优化设计并拉制了内径为1.1 mm的镀银空芯波导,实验测得当THz波的频率为2.5 THz时,传输损耗为8.6 dB/m,实现了THz波短距离的有效传输.

| Abstract: | Limited by serious material absorption and dispersion in THz wave band, efficient and long distance delivery of THz signal is one of important problems for constructing a compact THz system. Based on the transmission loss coefficient in metal waveguide obtained by perturbation method, the transmission loss properties of THz wave in metal-coated hollow waveguide varying with different metal materials and waveguide structure parameters are simulated. According to the numerical results, an Ag-coated hollow waveguide with inner diameter of 1.1 mm was designed and fabricated, and the transmission loss of THz wave was 8.6 dB/m at frequency of 2.5 THz as found in experiment, which realizes a short distance transmission with ultralow loss in THz region. |
