Well, for the argument, that could also be a neutrino jet, or any light particle with more kinetic energy than rest mass. The photon with a 0 rest mass is just a limit case. Also this is getting convoluted : have to take incoming DM <500km/s, and convert mass content to kinetic energy of collimated ejected relativistic particles that are light enough (otherwise they are less relativistic, and thrust is worse) and wall crossing (neutrinos, X rays). Mmm, you could even do the following : take incoming DM <500km/s, convert mass to energy, and with the energy of 1 million DM particles, accelerate 1 DM particle at relativistic speed. Would be dark matter powered dark matter jet rocket. Call that a "dark matter ramjet". Unless anyone can point me to previous publication or grant, I hereby take precedence on that concept
On the subject of wall crossing particles, anyone have any ideas on how a particle within the emdrive could be wall crossing at the big end but not the other walls given how it was designed?
Yes, long wavelength interaction w/ a condensate of bosons acts like a phonon generation.It's in here: http://cua.mit.edu/8.422_S07/BECinDiluteGases205-214.pdfMy head hertz.
The fact that operating at a frequency of 1937 MHz has a Q more than 4 times higher but a thrust force 1/2 as much as operating at a frequency of 1933 MHz is extremely problematic for all these inertia theories if they ignore the dielectric:1) McCulloch (Unruth radiation)2) the ZPF and Cassimir effect theoriesbecause the frequencies are practically the same (0.3% difference between them) yet the thrust forces differ by a factor of 2. Also the effect is very contrary to Prof. McCulloch 's model which is proportional to Q and inversely proportional to frequency. The thrust at 1937 is 1/2 as much while according to McCulloch's formula should be 4 times as high.All the ZPF theories have similar problems. This is a death knell for all of them if they ignore the dielectric.Again, an analysis of this effect needs a consideration of the dielectric thermoplastic. It may be difficult to consider the dielectric thermoplastic effect in all of this (including its nonlinearity), but the data all points in that direction. Einstein said to make things as easy as possible but never simpler than necessary. Any theory that ignores the dielectric cannot explain the results

somebody call the Nuclear Decommissioning Trust ?

If you do this the exitation propagates like a "phonon" in the condensate, which is a momentum transfer against the entire condensate (ie the "ocean to push against)Highly speculative, who wants to try a calculation ?

This analysis cannot explain the fact that the thrust would differ by a factor of 2 at frequencies less than 0.3% apart.Either this is due to:a) The actual cavity is not rotationally symmetric (the only hint of this is the off center inner circle)or b) the effect is not at all due to the mode shape but something to do with the dielectric not that related to mode shape (and even less related to Q )Based on my experience (I have not done an analysis yet) I favor b) since I cannot justify such huge differences for this geometry based on such a small frequency difference.There is something important we are missing hereI cannot justify such a huge difference on thrust

I have believed two impossible things today.
..Well the Cannae did provide a thrust too, and it isn't shaped like a bell. I previously asserted the pillbox didn't matter, and way way back in my posts, I advised to design the thing instead taking cues from coax cables, and cluster them, because of the Cannae tube. Later I dropped that in favor of clustering cone shapes in a wafer. Maybe I was right the first time.
