  text: 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.
