  Novel hollow-core THz waveguides featuring hyperuniform disordered reflectors
are proposed, fabricated, and characterized. The reflector comprise
aperiodically positioned dielectric cylinders connected with dielectric
bridges. The proposed waveguides are fabricated using a 3D stereolithography
printer. Optical properties of the fabricated waveguide are investigated
numerically using finite element method, as well as experimentally using
THz-TDS spectroscopy. The results confirm that proposed waveguides exhibit
sizable photonic band gaps (20%) even when relatively low refractive index
contrast used (resin/air). Position of the band gaps can be easily tuned by
varying reflector geometrical parameters.
