低损耗太赫兹波导及其成像应用
Low-loss terahertz waveguide and its imaging application
摘要
Abstract
High-performance terahertz functional devices have great significance in the generation, transmission and detection of terahertz waves. This paper reports a Kagome-type low-loss terahertz waveguide and its imaging applications. Firstly, anti-resonant waveguide theory was used to design a Kagome terahertz waveguide with lowloss transmission at 0. 1 THz, which has a theoretical loss as lowas 0. 012 cm-1. Secondly, the waveguide was fabricated by 3D printing technology. The experimental loss is 0. 015 3 cm-1, and the beam divergence angle at the end of the waveguide is about 6 ± 0. 5 degree. Finally, a reconfigurable terahertz imaging system was set up based on the waveguide, which realizes reflection and transmission imaging for a hidden blade and ore respectively. This technology has great application prospects in the underground long-distance exploration.关键词
