The development of waveguides is a key element in the technical maturity of the THz field. Suitably designed waveguides can provide innovative solutions for the most fundamental problems of THz energy transfer to the more advanced problems of THz spectroscopy. This presentation will give an overview of the chronological development of THz waveguides, starting from the initial time-domain experiments to the present state-of-the-art, highlighting breakthroughs. Experimental results obtained through waveguide characterization by THz time-domain spectroscopy will be presented and compared to well-known theoretical models, looking at issues related to energy coupling, attenuation, and dispersion, as well as single and multi-mode propagation.
