Abstract
Official abstract text for this publication.
A dielectric waveguide comprising a dielectric probe at each end, wherein the dielectric probes are arranged to transfer energy.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for fabricating a dielectric waveguide adapted to operate at frequencies between 60 GHz and 1 THz, the dielectric waveguide including a body comprised of a cladding and a core; the method comprising the steps of: injection molding both the core and the cladding using a thermoplastic material; and forming the body such that the core and the cladding together define a rectangular portion and tapered probe portions arranged at both ends of the rectangular portion; wherein the thermoplastic material comprises polyethylene, polypropylene or a combination thereof. 2. The method in accordance with claim 1 , wherein the injection molding step is performed only once when the dielectric waveguide is fabricated in a single mold. 3. The method in accordance with claim 1 , wherein the injection molding step is repeated when the dielectric waveguide is fabricated in multiple molds. 4. The method in accordance with claim 1 , wherein the tapered probe portions are tapered linearly along a longitudinal direction of the dielectric waveguide. 5. The method in accordance with claim 1 , wherein the dielectric waveguide produced has a propagation loss of less than 0.5 dB/cm. 6. The method in accordance with claim 1 , wherein the dielectric waveguide is a planar waveguide. 7. The method in accordance with claim 6 , wherein the cladding comprises two cladding layers, and the core is sandwiched between the two cladding layers. 8. The method in accordance with claim 1 , wherein the dielectric waveguide is adapted to operate at frequencies between 140 GHz to 220 GHz.
