List of Suggested Experiments
This page compiles suggestions for as-yet untested variations in experiment designs for EmDrive testing. When possible, links to the original suggestion and a brief description of the justification for this test are provided.
Note: For purposes of this list, the baseline for experimentation is considered to be a copper fustrum with either a magnetron or coaxial RF feed operated at approximately 2.45Ghz, similar to Shawyer's Feasability Study
- Replace solid endplates with a circular grid design similar to the endplates used by Cullen in his 1950's waveguide experiments, or a mesh as the one used for the glass windows in home-microwave-ovens, having a spacing between mesh or grids small enough such that only wavelengths smaller than that can get through. Purpose: to allow convection through the fustrum, eliminate buoyancy, thermal jet effects, natural thermal convection currents, and other gas effects.
- Place ferrite beads in the fustrum, either one large one next to an endplate or a pattern of them along a line in the longitudinal direction.
- Build small end plate out of Metglas or a similar material with high magnetic permeability like cast iron or any ferrite.
- Place a ruby inside near one of the ends to emit at 2.4 GHz as used in solid state Masers.
- Fill the fustrum with ammonia gas to emit at a 24GHz
- Separate resonance and attenuation chambers (proposed by WarpTech)
Experimental Measurement Setups
- Forum post by Rodal summarizing several prior posts. Purpose: to increase attenuation gradient in TE modes, having an axial magnetic field.
- Forum post by Flyby referencing earlier posts. Purpose: to test implications of statements in Prof. Yang's paper regarding magnetic thrust forces being approx. 100x greater on the end plates than the side walls.
- Forum post by aero, in response to Rodal's explanation of the history of maser development. Purpose: To produce maser-like amplification inside the fustrum.
