| Abstract: |
A flexible low-loss dielectric waveguide is made from a flexible low-dielectric constant hollow cylinder filled with high-dielectric constant powder. Alternatively, a rigid or semi-rigid waveguide comprises a groove formed in a low-dielectric constant substrate filled with high-dielectric constant powder.

First Claim:

What is claimed is:
1. A low-loss dielectric waveguide for replacing conventional electrical metallic waveguides and integrated circuits, comprising:
- (a) a waveguide housing made from a section of flexible low dielectric constant tubing which is operable to readily be bent to conform to any of various desired electrical waveguide and integrated circuit component shapes;
- (b) the interior of said section of flexible low dielectric constant tubing being entirely filled with a loose powder having low-loss and a high dielectric constant to provide a purely powdered waveguide core therein which conforms to the interior configuration of said flexible tubing;
- (c) a very low dielectric constant sealing means provided at opposite ends of said section of flexible low dielectric constant tubing for retaining said low-loss, high dielectric constant powder within said section of flexible low dielectric constant tubing and preventing spilling of said low-loss, high dielectric constant powder; wherein said waveguide can be bent to physically conform to the shape of various electrical waveguide and integrated circuit components as desired.
