The proposed manufacturing process followed by dip-coating post-processing provides an improved surface finish. Additionally, the terahertz output of the lens remains intact over the entire frequency range.}},

  abstract     = {{Additive manufacturing (AM) paves the way for low-cost production of optical and terahertz (THz) components such as waveguides, fibers, and lenses [1]–[3]. This work addresses the fabrication and THz characterization of a 3D-printed waveguide composed of cyclic olefin copolymer (TOPAS). Such a waveguide is a convenient and inexpensive tool in the development of THz interconnects, and in applications such as biomedical sensing.}},
