Abstract :
Terahertz time-domain spectroscopy (THz-TDS) measurements have been performed to characterise a photopolymer resin (FullCure Materialsreg) in the 0.1-3.5 THz range. A loss tangent less than 7- has been revealed up to 1.5 THz along with a weak frequency dependence of the real part of the optical index and the dielectric permittivity. This study underlines the promising applications of such a material for the fabrication of 3D THz imaging phantoms in the 0-1.5 THz range.
