Monomorphic , did you calculate Q values for these ...would you tell us what you came up with THNX FL
Roger calculated the Qu of my 2.45GHz, TE013, spherical end plate frustum at ~88k. He also told me the Qu of his 3.85GHz, TE013, sphetical end plate Flight Thruster was ~60k as measured.

The pic below is 2 parabolas, both with the concentric focus at 2.5" above 0. I think this would work with a very high Q at around 1.5 GHz.
The 2 parabola geometry looks very promising. Unfortunately I set FEKO to run a detailed sweep but my computer froze up so I lost all of that data. I will run again later, but here is a rough image.

With all the prior talk of gravity on this thread, this new paper maybe of interest.
Emergent Gravity and the Dark Universe
Recent theoretical progress indicates that spacetime and gravity emerge \break together from the entanglement structure of an underlying microscopic theory. These~ideas are best understood in Anti-de Sitter space, where they rely~on~the area law for entanglement entropy. The extension to de Sitter space requires taking into account the entropy and temperature associated with the cosmological horizon. Using insights from string theory, black hole physics and quantum information theory we argue that the positive dark energy leads to a thermal volume law contribution to the entropy that overtakes the area law precisely at the cosmological horizon. Due to the competition between area and volume law entanglement the microscopic de Sitter states do not thermalise at sub-Hubble scales: they exhibit memory effects in the form of an entropy displacement caused by matter. The emergent laws of gravity contain an additional `dark' gravitational force describing the `elastic' response due to the entropy displacement.
We derive an estimate of the strength of this extra force in terms of the baryonic mass, Newton's constant and the Hubble acceleration scale a0=cH0, and provide evidence for the fact that this additional `dark gravity~force' explains the observed phenomena in galaxies and clusters currently attributed to dark~matter.

Check that video of moving EmDrive. The one in the middle. That is Dr.White right? I did not see that video yet.
As Galileo once said: "and yet it moves".
You are being quoted in the IBTimes article you are responding to, in the above post, by the article's author (Mary-Ann Russon) as follows:
The paper was leaked onto the Nasa Spaceflight enthusiast forum on Saturday 5 November by an Australian EmDrive fan called Phil Wilson, who goes by the username "The Traveller". ....For his part, Wilson says that he chose to release the data onto the Nasa Spaceflight forum because he didn't believe AIAA intends to actually publish the paper.
Are you being quoted accurately by this IBTimes article's author? If so, what could possibly make you think that AIAA did
not intend to publish NASA's paper?

225 MV/m? Woohoo! When you re-post, please include all the parameters, like Cu?, input power W?, and whatever else you can to define the diagram. Could you also show the "B" or "H" field values not just E field?
As I said earlier, it would be great to compare apples to apples between the parabola, sphere and frustum, in the same material, same mode with the same antenna positioning. I think we would all learn something (maybe?) from this.
Thanks!

Well, when you see they start using images of jet engines as illustration for the EM drive, you know that the article is no longer concerned about telling the truth...
Sensational news and images... that's all what matters...apparently...

Good news.
Despite my health issues, I'm moving my workshop from home into a 10m x 10m space in a friends new warehouse as I need more space to assemble, test and ship my S band 0.1N thrusters starting mid 2017.
Plus it will need more space to test the S band YBCO LN2 cooled thrusters I have approved construction of.
Do hope Dave's news about EW is not correct.

While you are modeling conic sections you might as well try to fit in an ellipse. Seems there are a number of possible fitments.

Not sure if you should be congrat, due to your "act" and regarding your place in future history Phil. 
I am guessing that the result will be the eventual closing of this topic on nsf as a result of 2 suppositions on my part and my part only. Ew winding down and aiaa not proceeding with the publication by request.
Disclaimer...I have no special insight...only gut feel. I hope I am wrong.
That seems a rather drastic outcome even for such irresponsible actions.
It'll be a heyday for the conspiracy theorists.
"It works!
It's been tested!
It's been documented!
They won't publish!
It's being suppressed!"
Sigh.

Will you make an YBCO cavity independently?

And perhaps as a baseline the above models with flat base plates to compare with X-Ray's breakthrough!!
X-Ray and Monomorphic: Very nice work!! Congratulations!!

I too worry about this unauthorized release of non-confirmed EagleWorks data by Phil. EagleWorks was under the gun when the press got wind of some information last year and went nuts and NASA told the EagleWorks group to go quiet. I understand that.
I suspect and only just a feeling because the papers and information was not released per NASA's requirements that we may not hear anything from the EagleWorks group or NASA on this mess. NASA apparently hates bad unsubstantiated press and truthfully I don't blame them. IMHO Phil used bad judgement in doing this when we were told that the a paper was to be released in December, jeez Phil cancer or no cancer it was less than a month away.
IMHO more damage will come from this than good and that saddens me for it now will make my work tougher to validate anything good from my testing. And please Phil don't even reply to this as IMHO you may have done more damage than good and I have lost all respect.

Yes.
Due to the lack of power of the signal source which I ordered, we can not drive the power amplifier, the test has been suspended. Next week I will be sure to start the test.
