A Resonant Torsion Cavity Converter for Microwave Power Delivery
Year: 2026
Type: article
Abstract: The module set out in this paper is a resonant torsion cavity converter intended for delivering controlled microwave power for materials processing. Its operating principle is that a high-Q resonant cavity whose stored oscillating field is tapped through a loaded coupling loop, with the torsion term fixing the maximum field energy density adopted for the cavity sizing. The design is computed from stated assumptions throughout; it is simulated, not measured, and no prototype results are reported. The headline result is a delivered microwave power of 1.84e+03 W, obtained with drive power including wall loss of 1.96e+03 W with a computed efficiency or performance coefficient of 93.8 per cent where that measure applies, for a unit of mass 6.5 kg whose characteristic scale is a cavity volume of 0.012 m^3. A parameter sweep reported in the Results section shows how the output moves when the principal variable is changed, and the density of the working material, 8.9e+03 kg per cubic metre, sits about 54 orders of magnitude below the neutron-carrier density bound of 9.72e+57 kg per cubic metre, so the bound enters this design as a sizing ceiling and a margin statement rather than as an operating condition. The limitations are stated plainly: wall losses rise with the square of the field, so the design point is set by cooling of the cavity wall rather than by the coupling loop. Status: SIMULATED, NOT MEASURED.
