Abstract
In this paper a hollow core photonic band gap fiber is numerically investigated in order to obtain low loss waveguiding in the terahertz region (0.1-10 THz) of the electromagnetic spectrum. Waveguide design in this spectral region is a major challenge due to the high conductivity losses of metals and high absorption of thedielectrics. Numerical results show the eventuality to reach propagation loss two decades lower than the bulk absorption losses of the material used to make the fiber, over a wide range of wavelength.
