Abstract
A dielectric waveguide (DWG) has a dielectric core member that has a length L and an oblong cross section. The core member has a first dielectric constant value. A dielectric cladding surrounds the dielectric core member; the cladding has a second dielectric constant value that is lower than the first dielectric constant. A conductive shield layer surrounds a portion of the dielectric cladding.
Claims17
A dielectric waveguide (DWG) comprising:
- a dielectric core member having a length L and an oblong cross section, wherein the core member has a first dielectric constant value;
- and
- a dielectric cladding surrounding the dielectric core member, wherein the cladding has a second dielectric constant value that is lower than the first dielectric constant;
- and
- a conductive layer surrounding a portion of the dielectric cladding.

A method for transmitting a high frequency signal between components in a system, the method comprising:
- coupling the high frequency signal from a first component to a core of a dielectric waveguide (DWG) having a dielectric core with a first dielectric constant value and a dielectric cladding surrounding the dielectric core, wherein the cladding has a second dielectric constant value that is lower than the first dielectric constant;
- guiding the high frequency signal along a length L of the DWG;
- coupling the high frequency signal from the core of the DWG to the second component;
- and
- attenuating an evanescent wave traveling on a surface of the DWG with a conductive layer around an outer surface of the dielectric cladding.
