So If I understand you right, the join of the conic section and the tuning tube is 0.2244 meters up from the large end plate which is at the big end of the conic section. The small end plate is then 0.0376m up from that join. Or do I have it backwards? This is what I understand now.
But what is the size of diameter of the tuning tube and the tuning plate (small base plate)? They can't be the same size so their must be a gap.
Small plate 160 mm, .032", O2 Free copper walls, Silver ~.30 um on endplates.

Check back later, have friends over.
But I thought you were going to use silver plated ceramic for the end plates? I liked that idea much better than copper end plates because of my hypothesis that thrust may be generated by tunnelling evanescent waves. A thin silver plate on ceramic would have a lot lower barrier height than copper end plates, although 30 um might be more than I'd like to see.
One thing that bugs me about my idea is that the math seems to be readily available to check for momentum from tunnelling evanescent waves, but I don't have the knowledge to apply it.
But back to the C-E drive, the small end plate cannot be the same diameter as the inner diameter of the tuning tube. You may try for the same size but it won't move if it is wedged in tightly and you want it to move. What is your expected tolerance on the two diameters? Millimetres? Hundreds of micrometers? Tens of micrometers? Evanescent waves will escape through this gap and we want to see them.
I'm looking at about a .0125mm gap. I've ordered 2 plates. The second one I'll modify for evanescent wave actions with a set pattern in the silver for just them and set a conductive seal between the plate and sidewalls. I just would like to see what meep does in the modes with the antennas you selected and not too worried about them this run.

Fascinating reading about the history of the aether, its abandonment and reintroduction as "new aether" by Einstein.
https://en.wikipedia.org/wiki/Luminiferous_aether#Einstein.27s_views_on_the_aether
While reading up on resonator experiments concerning the aether, I found this which is thought-provoking:
http://vixra.org/pdf/1009.0057v3.pdf
Why over 30 years absolute motion was not detected in Michelson-type experiments
with resonators
V.V. Demjanov
He's basically saying all the negative results were wrong.
A strong advocate of the anisotropy of the speed of light (in material medium) revealed by the analysis of the Michelson-Morley experience test results, is the Australian phycisist
Reginald Cahill. A simple research on this name in arxiv.org will report the articles where he adress the subject.
Reginald Cahill has the same conclusion than
Demjanov of an apparent aether speed of 500 km/s with respect to the earth reference where anisotropy is detected.
Please save us time on this. WikiP reports delta-c/c <= 10
-17 from the most recent measurements. Is this the value taken by your two guys?
viXra is just about the last place to go for "information", btw.
OK, I peeked. This from arXiv critiques your sources

@SeeShell -
Yea, that's Ok. Meep on my computer can't resolve a 0.0125 mm gap. I'll go about looking for a resonance in the C-E frustum I have modelled. The inside faces of the ends are the correct distance apart, ckhigh = 0.26199999999999996 meters. I assume that's close enough
So I guess the model is correct. I can't think of another way to fit your numbers together and still get the right length. Well, I could move both ends, but that would violate your rule on the big end plate location.
So, I'm ready to chase resonance. Tomorrow.

The following article from
Reginald Cahill (
http://vixra.org/abs/1504.0125) lists several physical experiences concluding to the existence of a kind of absolute reference frame : "
Review of Experiments that Contradict Special Relativity and Support Neo-Lorentz Relativity: Latest Technique to Detect Dynamical Space Using Quantum Detectors"
In his article that you refer to, ("
A criticism of ”gas mode ”reinterpretations of the Michelson-Morley and similar experiments."),
Daniel Shanahan far from disputing the thesis of
Reginald Cahill on the existence of an absolute frame, writes in support to it : "
However, it is also suggested here that whether or not the absolute frame urged by these investigators is detectable, there exist compelling reasons for considering the alternative Lorentzian approach to relativity that did suppose such a frame".
Now on the analysis of the speed of light in material medium, it is really strange that
Daniel Shanahan call it "Reduced
phase velocity V of light". For me this speed is a real speed (with energy transport) and not a phase speed which can be as great as we want. Moreover the Maxwell equations (which are fully Lorentz transformation compatible) give a clear and invariant status to the light speed in a material medium as soon as this medium is characterized by well defined permittivity and permeability. Do you suggest that permittivity and permeability depend on the speed of the observer who measure them ?

Thoughts to the gap...
Shell, is your favorite target mode still TE012? If yes the field strength(E) for this mode tend to zero near the "edge" of frustum and endplate. It is zero in the corner. There will be also no current flow between the frustum and the plate.
So if the gap is small its not "visible" from the viewpoint of this mode.
For some other mode shapes the gap can work as a slot antenna, it can radiate, not in the sense of evanescent waves.. The most interesting point is the length of the slot and thats the circumference in your case(not only the width of the gap is important).

It's easier to model in meep if it's treated as connected or a small gap which aero likes, in real life I'm going around the circumference of the plate with a beryllium copper gasket that will electrically connect to the frustum and seal the endcap but allow it to slide freely.

I'm still going to pursue the TE012 mode even though it seems to be tough the gains outweigh the toughness. And it is because of the gains seen in thrust a potential red flag to persue.

Good plan. For all the modes which produce currents thru the gap, a good galvanic contact is necessary. While moving the plate the S-Parameter signal will look a little noisy that depends on the contact between the frustum and the plate(will be stable again after movement). The resonant frequency could be a little bit lower than calculated for a given length (MHz range, caused by longer current paths) if the metal seal is at the outer side.
For TE01p that is not the case, no noise while moving the plate.
Again its a good plan. No better idea at the moment
NSF-1701 update - Last night, I finished the test stand and discovered that the beam support wire stabilized the vertical oscillation so well that I have no need for the oil bath dampener. This lowers the overall weight of the assembly and simplifies it. The laser is end-mounted, throwing about 20 feet to the target. There is significant dispersion, but small interference patterns from the panoramic mirrow reflector generates small dot patterns that I can use to calibrate. 1 gram throws it off the target. 500 mg is full target vertical travel. While this will not show resolution of 1 mg, anything over that should be readable. Approximately 20 mg will equate to 200 millinewtons of force. Anything smaller than that is not practical for any home-builder IMHO. So...the galinstan arrived and it is ready to go. But I have a weekend to enjoy first
So, been thinking about a suitable lab in case further experimentation on NSF-1701 is desired. Here's a stream of consciousness list of the test gear I'd like to get my hands on (all calibrated with computer interface, RF stuff 3 GHz minimum):
(...)OK, what are we missing...hmmm
<edit> I stopped counting at $100,000
Tools to make advanced frustums wrt machine shop tools.
Good catch shell, of course...looks like my estimate doubled to about $400K total not including building.
So about the same capital cost as a gas station, plus say $250K a year in salaries and another $100K in materials/misc. So around $1m and two years for a useful prototype (if such a thing is even possible). That's a large grant or an average sized early stage venture capital project. Doable, but difficult. At around 200N/Kwh you're approaching the output of a turbojet, that's certainly interesting if it can be achieved. Also, um if the drive doesn't pan out is there any chance the research could lead to a better way to cook a potato?
For venture capital my gut is telling me that you'd need thrust outside of the noise range, say 1N and some indication that better can be reached. A working theory that does not violate CoE or CoM would also be helpful, as would some press releases before seeking funding.
If 1N/kW could be proven, every aerospace company on the planet would be building these. Yes, it's that big a game-changer. Mind you, if I understand the physics correctly, a 100% efficient unit would be 1KN/KW right? That means currently we're only talking about a 0.1% efficiency (1N) and that would be enough to change the face of spaceflight. Figure this thing out and the money will come at you like a firehose (my conjecture).
It is way, way too early to start jumping to conclusions. Anyone who does is not being fair. Until open and replicated experimental data is available, it's all noise as far as I'm concerned. As matters stand, there is nothing that is open and replicated.
The ironclad test is a space test. This cannot readily be fooled with artifacts. What's required for that is twin units in reasonably close proximity, one powered and one not, and in all other respects identical.
I know I'm a broken record, but IMHO there are many more uncontrollable factors in low earth orbit than in the lab, considering the minscule power available for the thruster on a cubesat.
In a 6u cubesat, we can get up to about 400W from the solar arrays and store enough to do a few KW of output for short periods (several minutes). That avionics bus design is on my computer now (I do avionics for a living).
TE012 excitation
For the new dimensions you provided I get a very good TE013 excitation at 2.47 GHz, according to TT's spreadsheet.
This is for flat ends. Do you plan flat or spherical ends?
External magnetron coupled to 4 loops internally at H plane 180 phase shifted […] And two additional and equal length but added lambda/4 for a 90 phase shift for a total of 180 deg on each. Quad loops ~1/5 WL 10 gauge copper loops excited in the H plane supported by the vertical tuning quartz rod.
Could you post a drawing showing the antennas shape and placement?
If I gave you a 3D printed form for the spherical base would that help to form it? Unforunately I only have 11" diameter - 295 is about 11.6" - just a little too big for my new big printer, but I could do 4 identical quarters and super-glue them together... Actually I know a firm here in Baltimore that can copperplate the plastic for reasonable money - but it's probably $1K at a guess... It would be several microns thick...

I'm not clear as to whether you are referring to the fact that right now you have succeeded to eliminate all drafts, air convection from your garage so that the beam is stable and the beam does not oscillate on its own or whether you are referring to damping an impulse response. How fast does it damp out an impulse? If there is enough friction so that it damps out the initial impulse response resulting for example from applying an extra weight, you are OK. On the other hand if it does not damp out an initial impulse, you may still need the oil damper.
Have a favor to ask my NSF pals here...on my 2 hour guest appearance next Thursday/Friday on the digital radio show, the last hour is being left open for callers questions/comments. Rather than the general audience, I'd like NSF folks to call in. It will be fun to hear your voices and get your perspective on the concept/project whether for or against the theories out there.

I was surprised as well. My guess is the rigid steel wire is doing most the work, plus there is about twice the mass on the knife edges. Verticle dampening is quick, horizontal dampening takes more than twice the time, but has improved. Random airflow does not affect it as much due to the increased mass i believe. This was a real problem before. Verticle dampening of 1 g weight insertion is less than 30 seconds and almost no jitter.

You have me excited rfmwguy! It will be interesting to compare the two tests as we eneded up with similar setups.
Did I mention to you that you could make a tiny pinhole in a plastic business card with a hot pin (cheap and dirty pinhole lens) and put it in front of the laser to clean up the beam to get you a very small dot? I was surprised at how well this old school pinhole lens worked.
