Abstract :
Dielectric-lined hollow metallic waveguides provide a solution for guiding THz pulses that exhibits low losses, excellent mode quality and low dispersion. We analyzed mode structure and dispersion using THz near-field microscopy, time-domain spectroscopy and numerical methods to describe THz pulse propagation.
