Summary
Todd Desiato (@WarpTech on Nasaspaceflight forums) has put forth a theory that explains the EMDrive's thrust as a result of the Polzarizable Vacuum model of General Relativity.
Explanation of the Polarizable Vaccuum Model
The PV Model was developed by Harold Puthoff as an alternative explanation of gravity and electromagnetism. It is a scalar theory of gravity, which posits that spacetime has a refractive index, much like glass, and that the presence of mass causes spacetime to refract energy, resulting in gravity.
Application of Theory to the EmDrive
According to @WarpTech, the EMDrive function mimics this refraction, but only across the specific wavelengths that correspond to its internal geometry. As microwave energy builds within the fustrum, the energy becomes concentrated at the larger end. Because the energy density is not evenly distributed, the refractive index has a gradient from the big end to the small end. This mimics gravity at the wavelength of microwaves. As the microwaves "fall" towards the small end, their wavelengths are attenuated and momentum is absorbed by the fustrum as the group velocity goes to zero near the small end. The result is propultion in the direction of the small end of the fustrum.
Status
There is not yet enough experiemental data to validate @WarpTech's theory. Additional data, particularly from superconducting EmDrive experiements, may result in data that is relevant to validating or disproving this theory.
Predictions and Evidence
Notably, it is solely the geometry of the fustrum that is relevant to this effect under @WarpTech's theory. A higher power level or higher Q would not result in higher thrust. The Q factor is only relevant as a measure of the stored amount of energy. The fustrum itself does not need to resonate, and to this end, @WarpTech has proposed decoupling the resonance chamber from the attenuation chamber. He suggests a design where resonance is induced in a long cylindrical waveguide, then energy is periodically dumped into a fustrum to attenuate. So far this design has not been tested.
