Résumé

Hollow core circular waveguides are promising candidates for guiding terahertz waves. In this study, we numerically and experimentally investigate the coupling parameters under fixed coupling conditions for different waveguide diameters. Terahertz time-domain spectroscopy is employed for experimental of study mode propagation. Multimode behavior is observed above 0.3 THz, whereas waveguides with larger diameters exhibit reduced number of interference peaks and low single-mode loss. Efficient propagation of terahertz radiation in these waveguides may find applications in telecommunication and spectroscopy.
