This is a remarkable achievement if it can be proven to perform as suggested. I have a problem with the concept of force generation without ejecting mass(or energy). The continual application of a device such as this will result in a significant amount of kinetic energy along with momentum being imparted upon the system. Clearly, a violation of conservation of momentum results.
Is there some explanation as to why it is possible to violate this conservation law since it has been proven correct for many years. If the only real proof is mathematical then I suggest that the authors locate the errors in their work. If a working model has been constructed then it should be replicated as soon as possible since it has major implications for physics theory. My suspicion is that this fall into the category of "too good to be true".

The last line of the paper confirms that experimental thrust measurements have been made at 1kW input power. The unpublished test results show a large number of thrust measurements at input powers up to 2.5kW. The mean specific thrust obtained is close to that measured in the SPR flight thruster tests. Note that the Chinese thruster, if deployed on the ISS, would easily provide the necessary delta V to compensate for orbital decay, thus eliminating the need for the reboost/refueling missions. The original 2010 paper, the translation and the unpublished test results are given here: NWPU 2010 paper (Chinese) < http://www.emdrive.com/NWPU2010paper.pdf> NWPU 2010 paper (English translation) < http://www.emdrive.com/NWPU2010translation.pdf> NWPU 2010 unpublished test results < http://www.emdrive.com/NWPU2010testresults.pdf> Conclusion : ... With 1000W microwave input, using brass as the material of the cavity, using the classical theory of electrodynamics, the maximum theoretical thrust produced in modes TE011 and TE012 is 411mN and 456mN respectively, and the practical measurements are 214mN and 315mN.
