Abstract
An apparatus includes a tube including an inner surface, an inner diameter, and a length. The apparatus also includes a coil spring. The coil spring includes an outer surface, an outer diameter, and a plurality of coil elements arranged along a length of the coil spring. The coil spring can be positioned within the tube and the outer diameter of the coil spring can be less than the inner diameter of the tube. The coil spring can form a waveguide. Related methods of manufacture and systems are also described herein.
Claims10
An apparatus comprising:
- an outer tube formed as a single body having an inner surface, an inner diameter, and a length greater than 1 meter;
- and
- an inner tube having an inner surface, an outer surface including a dielectric material on the outer surface, an outer diameter, and a helical-shaped groove formed on the inner surface and extending along a length of the inner tube, wherein the helical-shaped groove is configured to propagate a millimeter electromagnetic wave in an HE11 mode and the inner tube is positioned within the outer tube and the outer diameter of the inner tube is less than the inner diameter of the outer tube.
A method comprising:
- forming a plurality of corrugation features on a first side of a sheet of metal stock, the sheet including a first edge and a second edge;
- forming the sheet of metal stock into a first tube;
- welding the first edge and the second edge together to seal the first tube, wherein the sealed first tube forms a corrugated waveguide;
- and
- inserting the sealed first tube into a second tube to form a multi-piece corrugated waveguide.
A method comprising:
- receiving a sheet of metal stock having a first surface, a first edge, and a second edge;
- receiving a corrugation element immediately adjacent to the first surface of the sheet of metal stock, the corrugation element including a plurality of corrugation features;
- forming the sheet of metal stock into a first tube containing the corrugation element within the first tube;
- and
- welding the first edge and the second edge together to seal the first tube, wherein the sealed first tube forms a multi-piece corrugated waveguide.
