Hope so...its a hot potato subject you know.That's what I've been saying! The EM Drive mimics gravity over a narrow bandwidth of the EM spectrum, near the cut-off modes of the cavity. There is a gradient in both the energy and the power, and this makes the thrust. "UP" is toward the small end in this gradient. Resonant modes at the small end fall down to the big end, so the frustum moves up to compensate. As long as water keeps flowing over the falls, it keeps rising. I don't care if the water bounces at the bottom of the fall, as long as it "eventually" dissipates "down there". So we want to inject power as a circular standing wave at the small end and make it as small as possible. Simple as that, gravity will do the rest. The question is, how much power is required? That's what I'm trying to figure out!ToddPS: That Trombone Bell is looking better and better!
Cost to generate clean RF goes up much faster than linear as frequency increases into the millimeter range so this will be a cost driver - hence the need to find the "sweet spot" for N/kg AND N/$. Its late and I may not be expressing this very well.Herman
... snip ...Indeed - I'll do so. Run just completed and it took quite a while serialized to one CPU, as you said.And, having run the comparison, we're out of sync. I used the apt-get install meep approach, and evidently that's in adequate.I'll next turn my attention to reviewing the recompilation of everything (hmph) and will try to reproduce the reference csv with small error across all cells before moving on to trying to get an MPI version that also matches closely.Thanks,Ed

And what is the maximum intensity that, say, copper can withstand without melting, exploding or whatever?Your difficulty isn't that the copper melts, instead you have arcing inside the waveguide and resonator. The gas (or lack thereof) inside the waveguide or cavity determines when this happens. Arcing happens more readily in vacuum than in air than in https://en.wikipedia.org/wiki/Sulfur_hexafluoride. The latter, Sulfur Hexafluoride, is used in large Van de Graaf generators to prevent arcing. The gas inside the resonator is a type of dielectric, so you'll have a change in the group velocity and other math to consider.To your other question, what is the largest size microwave source can you buy: Big. They are not controlled devices. If you accidentally melt a busload of people with one, that will likely change.The largest microwave sources I found were Gyrotrons. There is a company, "Gyrotron Technology Inc." that offers custom and semi-custom gyrotrons with remarkable microwave sources available. I have not reached out to them for pricing or capability details.Along gyrotrons, the most powerful manmade source of microwaves are klystrons. SLAC uses 150 megawatts (pulsed) S-band (3GHz) klystrons and 1.25 MW CW klystrons! But we don't wand to ignite the plasma of a tokamak or power a particle accelerator, and we're not quite yet feeding lift engines of a mothership.Below, a 65 MW SLAC klystron:

I am still trying to put all the pieces back together in a comprehendible way.Embarrassment - are you kidding? You are one of the most courageous people I know, and one of few here. You are hurling decades of learning and practical experience at a difficult, ambiguous problem, in full view of the public and without a shroud of anonymity, despite knowing the possibility of being wrong and despite knowing that [at times impolite] reviewers are waiting for a misstep. You know going into it that you might err, and whenever you do you publicly take ownership of the mistake and detail how and why you were wrong. And then you go right back to working on it again!Please - and you don't need to hear this from me, but - just keep going. If everyone who was capable simply did what you do routinely, our society might be much closer to cracking this right now. So let me just take the opportunity to say thanks. And kids, if you're reading, know that this man Todd is a man of courage!

Do not go gentle into that good night, Old age should burn and rave at close of day;Dylan Thomas
visiting SpaceX and Eagleworks with my roadshow 100mN/100W EMDrive total system. Might as well drop by MythBusters while I'm in the US. Maybe also do a few US talk shows, so millions can see an EMDrive madly spinning on it's cordless rotary test rig.Should be fun as the physicists who claimed the EMDrive was impossible and have held this tech back for 15 years, scatter for cover.
Very interesting line of thought. Since in this concept "The EM Drive mimics gravity over a narrow bandwidth of the EM spectrum, near the cut-off modes of the cavity" then it would be interesting to see how the overall effect varies with the cut-off mode and frequency of the cavity (i.e. 1.2 Ghz, 2.4 Ghz. 5.8 etc). You mention "as small as possible" which would seem to imply as high a freq as possible but how does it vary (linear, exponential, ). Cost to generate clean RF goes up much faster than linear as frequency increases into the millimeter range so this will be a cost driver - hence the need to find the "sweet spot" for N/kg AND N/$. Its late and I may not be expressing this very well.Herman
Extracting only the necessary data to csv and compressing the csv file with 7zip or xz will provide up to an order of magnitude decrease in file size.
