  • Title: Bending loss of terahertz pipe waveguides.
    Author: Lu JT, Hsueh YC, Huang YR, Hwang YJ, Sun CK.
    Journal: Opt Express; 2010 Dec 06; 18(25):26332-8. PubMed ID: 21164983.
    Abstract:
    We present an experimental study on the bending loss of terahertz (THz) pipe waveguide. Bending loss of pipe waveguides is investigated for various frequencies, polarizations, core diameters, cladding thicknesses, and cladding materials. Our results indicate that the pipe waveguides with lower guiding loss suffer lower bending loss due to stronger mode confinement. The unexpected low bending loss in the investigated simple leaky waveguide structure promises variety of flexible applications.
