Abstract
A dielectric waveguide coupling system for launching and extracting guided wave communication transmissions from a wire. At millimeter-wave frequencies, wherein the wavelength is small compared to the macroscopic size of the equipment, transmissions can propagate as guided waves guided by a strip of dielectric material. Unlike conventional waveguides, the electromagnetic field associated with the dielectric waveguide is primarily outside of the waveguide. When this dielectric waveguide strip is brought into close proximity to a wire, the guided waves decouple from the dielectric waveguide and couple to the wire, and continue to propagate as guided waves about the surface of the wire.
