ion drive is not an EM-drive, is not even propellantless propulsion.

Thanks, hadn't seen it yet. Took a quick skim.
Interesting approach. I liked that they did an on axis null run, as well as with atmosphere and without.
I would have maybe also done a reverse on axis null run, as well as both z-axis runs to be completely thorough in that regard.
The next test cycle would be interesting with a larger cavity, however, same drivers.
Then another with same cavity, however up the power.

This seems to be a win.

I'm not seeing a clear description of the RF feed physical arrangement. Is all the RF equipment on the force balance, or do we have to account for photon pressure inside feed lines?

That leak appears to be their 2015 paper that wasn't accepted. It still references the original frustum.

That article is strong in speculation, weak in evidence. As far as I understand it, the thruster that China is testing is an Ion Thruster. I can see how one could get confused when writing this piece. Also, we know unequivocally that the X37B is testing a hall thruster at the moment. Once again, I can see how the author could confuse the two concepts. As far as I can tell, this whole thing looks like a series of rumors started by a guy over at NSF although I hope I'm wrong about that. He posted a few weeks back making all these claims and then this article which matches perfectly with his claims appears. Peculiar timing for sure.

Well folks, looks like the "leaked" paper and all the rumors have been sourced to an NSF member that goes by the name "TheTravellerReturns." This particular NSF user has a history of rage-quitting their forum only to come back. Has denied he was the source, although that denial is hard to refute now that Ibtimes has outed him as the original articles source. Has spread untrue/fantastical rumors about the testing of the EmDrive on various rockets. I find this type of behavior appalling. This does not bode well for the EmDrive community.
