Description

technical field

[0001] The invention belongs to the field of terahertz technology and discharge plasma technology, and in particular relates to plasma terahertz waveguide technology. Background technique

[0002] Terahertz (THz) wave refers to the frequency of 0.1 ~ 10THz (wavelength 30 ~ 3000μm, 1THz = 10 12 Hz) range of electromagnetic waves. THz technology is widely used in many important fields such as biomolecular identification, material diagnosis, astronomical observation, atmospheric and environmental monitoring, wireless communication, national security and anti-terrorism. In the THz application system, the transmission channel of terahertz waves—the waveguide is an indispensable key part.

[0003] Photonic crystals are artificial microstructures with periodic arrangements, which have the characteristics of photonic band gap and photonic localization, and can be used to make terahertz waveguides. In the photonic forbidden band of photonic crystals, electromagneti...
