We report on the characterization of 3D-printed hollow core Terahertz waveguides with metal wire inclusions over a frequency range of 0.2-1.0 THz using standard THz time-domain spectroscopy. We observe single-mode broadband THz propagation in these waveguides, and measure the loss coefficient and the mode effective phase index. Our measurement data agree well with predicted values obtained from numerical simulations.
