Any objections to adding the TE012 test where no thrust was measured as a line in the chart? See the Brady et.al paper page 18. --Sfrank (talk) 13:16, 5 June 2015 (PDT)

The Brady et.al. report reads:

<<We performed some very early evaluations without the dielectric resonator (TE012 mode at 2168 MHz, with power levels up to ~30 watts) and measured no significant net thrust.>>

Yes several objections, noted in the thread. It was performed at the very earliest in NASA's testing program, @TheTraveller made an argument that it was conducted at the wrong frequency, not enough details are given in the Brady report to resolve this. Brady et.al. did not even include that test on their table of results. Suggest to wait until NASA conducts the tests without a dielectric this summer (with a magnetron).

Notice that Brady et.al. doesn't provide the Q quality factor of resonance. If they would have provided the Q, I would be in favor of including it, since it would constitute a proof that a test was conducted at high Q giving no thrust. But unfortunately they didn't provide the Q. If the Q was near zero, it would be no surprise that they registered no thrust force, because the EM Drive is supposed to register a thrust measure only when the cavity is excited at resonance. Essentially if a Q is not provided , and they register no thrust, one doesn't know what the reason is for this.

We should start filling the table with Prof. Yang's results (even though it is not possible to fill the whole table, they are merited because they were published in a peer-reviewed journal, and they were conducted at a University. They have a different way to measure the Q - it should be noted-

OK, adding Yang's results. How about Brady et.al's Cannae tests? There's no Q or Mode data but we have Freq, Watts and measured thrust.--Sfrank (talk) 18:50, 5 June 2015 (PDT)
