| 20100135626 | WAVEGUIDE HAVING A CLADDED CORE FOR GUIDING TERAHERTZ WAVES - A waveguide for guiding terahertz waves with wavelength ranging 0.1 mm-3 mm, includes a cladding tube made of a metal-free dielectric material, and a core filling a transmission space defined by the cladding tube. The core has a minimum width or diameter larger than the wavelength of the terahertz wave guided by the waveguide. The thickness of the cladding tube is smaller than the radius or one half of the width of the core. The core has an attenuation constant for the terahertz waves lower than that of the cladding tube. The waveguide guides terahertz waves mainly inside the core, and has a simple construction. | 06-03-2010 |
