We experimentally demonstrate broadband terahertz (THz) pulse propagation through hollow core fibers with two or four embedded Indium wires in a THz time-domain spectroscopy (THz-TDS) setup. The hybrid mode is guided in the air core region with power attenuation coefficients of 0.3 cm(-1) and 0.5 cm(-1) for the two-wire and four-wire configurations, respectively.
