Experiment on loss characteristics for 0.14 THz folded waveguide slow-wave structure
-
摘要: 分析了两种常用来计算等效电导率的理论公式,并加工了折叠波导慢波结构进行冷测实验验证。在粗糙度为0.3 m时,0.14 THz电磁波在无氧铜中传播的等效电导率约为4107 S/m,这与已有理论公式的计算结果并不一致。最后初步讨论了这种不一致产生的原因,并提出了修正相关理论公式的想法。Abstract: The most commonly used method was adopted to calculate the conductivity loss. This paper analyzed two kinds of theory formula to calculate the effective conductivity, and fabricated the folded waveguide slow-wave structure for testing. The test result shows that the effective conductivity of 0.14 THz folded waveguide structure in oxygen free copper is 4107 S/m when the surface roughness is 0.3 m, which is not consistent with the theory calculation. Finally, the reason for this discrepancy was discussed, and a modified theoretical formula was put forward.
