利用太赫兹时域光谱系统对三种反谐振波导的太赫兹谱进行了研究,这三种波导分别是PMMA管型波导,PMMA自支撑结构波导和SiO_2管型波导.该研究验证了三种波导的太赫兹传输基于反谐振理论,并在实验上实现了PMMA自支撑结构波导超过2 THz的宽光谱传输.同时,对基于反谐振原理的太赫兹物质传感进行了理论和实验分析,为物质探测提供了一种可行的手段.
The terahertz spectra of three kinds of antiresonant waveguides are studied by using the terahertz time-domain spectroscopy system. The three waveguides are the PMMA tube waveguide, the PMMA self-supporting structure waveguide and the SiO 2 tube waveguide, respectively. The study verifies that three waveguides The terahertz transmission is based on the antiresonance theory and experimentally achieves broadband spectral transmission exceeding 2 THz for waveguide with self supporting structure of PMMA.At the same time, theoretical and experimental analysis of terahertz sensing based on antiresonance is carried out, Probing provides a viable tool.
