A novel hollow-core THz waveguide enabling efficient THz wave propagation over 72 cm long length, is presented in this study. THz waves guiding in a hollow-core is achieved by an out-of-plane Photonic Band Gap (PBG) crystal cladding with a design inspired from the technology of hollow core PBG-crystal fibers. These fibers developed in the optical domains have demonstrated exceptional performances such as single mode propagation of light with low attenuation on kilometer length scales. The properties of the PBG guiding mechanism to forbid THz waves extension in the crystal cladding is exploited for enabling low-loss propagation in a waveguide fabricated with a highly absorptive material (ex. silica).
