Abstract

The high bandwidth available in the terahertz domain is promising for non-destructive evaluation (NDE) and inspection applications. Although 3D-printing offers great flexibility and fast design iteration when developing quasi-optical components for such applications, common 3D-printing materials tend to suffer from high dielectric loss at terahertz frequencies, exacerbating signal-to-noise ratio issues that arise due to the low output power of typical terahertz sources. Cyclic Olefin Copolymer (COC) has favourable properties at terahertz frequencies, and has proven useful in developing custom quasioptical components. In this work, we present a variety of 3Dprinted lenses used in NDE and inspection applications.
