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

Design/Shape Modifications

1. Replace solid endplates with a circular grid design similar to the endplates used by Cullen in his 1950's waveguide experiments. Purpose: to allow convection through the fustrum and minimize thermal jet effects.
2. Imbed ferrite beads in the fustrum, either one large one on an endplate or a pattern of them on the sidewalls.<ref>Forum post by Rodal summarizing several prior posts. Purpose: to increase attenuation gradient in TE modes.</ref>
3. Separate resonance and attenuation chambers (proposed by WarpTech)

Fustrum Material Variations

1. Build small end plate out of Metglas or a similar material with high magenetic permeability.<ref>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.</ref>
2. Fill a 24Ghz fustrum with ammonia gas<ref>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.</ref>
