Characterisation of olefin copolymers using terahertz spectroscopy

Terahertz (THz) time-domain spectroscopy has been used to characterise cyclic olefin polymers in the range 0.2-1.2 THz. A comparision of the optical properties of the polymer with standard materials currently used to fabricate THz optics, namely high density polyethylene and Picarin, is also presented. This comparison suggest that olefin copolymers are potential candidates for manufacturing optical components for the GHz and THz range.
