An overmoded dielectric-lined waveguide, particularly for the 0.03 to 3 terahertz frequency range, is disclosed with performance advantages relative to prior dielectric-lined waveguides, cost and size advantages relative to corrugated waveguides, and with coupling, bandwidth, and cost advantages relative to micro-structured-fiber waveguides. The waveguide comprises a single-clad flexible microwave laminate rolled into a cylinder with said copper surface on an outside of said guide tube and said dielectric surface on an inside of said guide tube. The rolled laminate is supported inside a metal tube. The same method of achieving the structure needed for efficient guiding of HE11 mode may be applied to a conical tube to make a low-cost efficient overmoded tapered waveguide transition for the 0.03-3 THz range.
A waveguide for the transmission of radiation at nominal frequency f0, comprising:
A method for use with a radiation at nominal frequency f0, the method carried out by an apparatus comprising a laminate comprising a single copper layer bonded to a dielectric layer, said laminate formed into a guide tube with said copper layer on an outside of said guide tube and said dielectric layer on an inside of said guide tube, a support tube encasing said guide tube, said support tube further characterized as having a minimum inside diameter di greater than 2λ, where λ is the free-space wavelength at said frequency f0, the method comprising passing said radiation at the nominal frequency f0 into a first end of said guide tube and making use of said radiation after said radiation is emitted from a second end of said guide tube.
A method for use with radiation at nominal frequency f0, and with a laminate comprising a single copper layer bonded to a dielectric layer, the method comprising:
