A multiple-joint transmission line based on the principle of the periscope was developed to realize the flexible guidance of terahertz (THz) waves. The transmission line has a slightly larger diameter than the standard plastic hollow-pipe waveguide, sufficient stability, low transmission loss, ultrabroadband spectrum, and low dispersion. The transmission line is evaluated using a THz time-domain spectrometer consisting of reflective two-dimensional electro-optic sampling with a high-speed complementary metal-oxide semiconductor camera.

太赫兹地区的超宽带和低色散多点传输线

开发了一种基于潜望镜原理的多关节传输线，以实现太赫兹（THz）波的灵活导引。传输线的直径比标准塑料空心管波导稍大，具有足够的稳定性，低传输损耗，超宽带频谱和低色散。使用THz时域光谱仪评估传输线，该光谱仪由反射二维电光采样和高速互补金属氧化物半导体相机组成。
