In this article, a hollow core photonic band gap fiber is numerically investigated to obtain low‐loss waveguiding in the terahertz region (0.1–10 THz) of the electromagnetic spectrum. Waveguide design in this spectral region is an arduous challenge due to the high‐conductivity losses of metals and high‐absorption of the dielectrics. Numerical results show the possibility to reach propagation loss two decades lower than the bulk absorption losses of the material used to fabricate the fiber, and low dispersion over a wide range of wavelength. © 2009 Wiley Periodicals, Inc.
