) with FEKO and found similar results.
There seems no connection to the function of the EMDrive cavity at all but the paper seems to be conclusive regarding the field point of view.
They simply found resonating modes in undersized dielectric particles (compared to the much greater wavelength in free space of the exciting field). The effective wavelength is smaller in a particle with a high dielectric constant and when resonance take place# beside a small damping factor the field strength grows up to to an amount much higher than the field strength of the sourounding (exciting) field.
This is interesting regarding the in coupling properties but not magic.

As an old Cold Warrior, I have to say it's sad to see how Russian science appears to have deteriorated after the fall of the Soviet Union.
Ditto the old Cold Warrior and deterioration, as well as fracturing of focus and goals of Soviet science. When everyone was dedicated to defeating the Main Enemy funding was widely and (relatively speaking) lavishly available.
Now it is my understanding from a few of my contacts still active in research there that funding is even harder to obtain than in the "West" and research is even more risk or failure or embarrassment averse that it is here. So if EMDrive work is going on there I would be most surprised if wasn't either VERY black or those in charge are VERY confident of positive results.
Having said that however the paper does look as if it may have some points of interest. Does anyone have a link to the original Russian?

Just today they lanuched the "Mayak". One of its purpose is to clear the space debris from our orbit.

We just need to be careful not to fall into the "wishful thinking" trap.
As there is no official press communication coming from Gilo industries, there is no 100% certainty that Gilo Industries is involved in EMdrive research/development.
IIRC, there are only circumstantial indications, based upon investment of Gilo in Shawyer's company...
It is therefor prudent to say that Gilo Industries MIGHT be involved in EMdrive research/development...
It is not because there is a positive attitude on this forum, to go along with the idea it might work, that we should omit the possibility it might just not work out....
Let us not forget that at this moment, a considerable part of the active forum participants just mentally pretend to accept the EMdrive. Such a positive attitude is needed to get rid of both pro/contra bias, and keep searching till a conclusive answer is to be found (be that a positive or negative one).
I find it admirable and in the true spirit of scientific curiosity that so many knowledgeable people try to come up with ideas and possibilities to explain what "might" be happening, even if there is still serious doubt about the validity of the test results obtained so far.... -

Oh I agree -I wasn't very clear when I posted last night - long day and late night !! Their space research and work is quite good and very impressive. I was bloviating about some of their basic science research; which even there I may have been talking out of turn. My apologies if anyone was offended.
BTW - their engineering/manufacturing approach to aerospace (the only area with which I have direct experience) has some interesting and valuable techniques. I recall analysis a team I was on did on their system engineering approach to satellite design - this was back in the late 80's or early 90's IIRC..
In this we examined several generations of sats spanning maybe 20 years of development. One of our conclusions was that once they found something that worked they stuck with it. An example is a specific multi-pin space rated connector. It was something like a D-Sub connector family. Don't recall their name for it. It was vacuum rated and apparently quite able to handle LEO radiation levels. IIRC they had an equivalent to a DA-15, DB-35 and DC-37 - not the same as those just fairly similar. The point is that once they got it working they used it just about EVERYWHERE. It even started showing up in new versions of man rated vehicles. All sat builders used it because it was both a cost and risk reducer. It wasn't particularly light but with the throw weight capability of their boosters that wasn't a big problem for them (yes every gram does count BUT so does every point of risk too).
Why is this relevant to EMDrive. Well for the experimenters it is useful to remember you don't have to re-invent every wheel. If some technique or equipment has proved itself in RF work or some other aspect of building an EMDrive test bed, it may well be worth considering it. If a particular issue or questions seems to have solutions - research them/study them/ learn them. Discuss it here - there are literally centuries of experience and knowledge here as well as brilliant and creative people who will provide inputs, answer your questions and sometimes even provide solutions - FOR FREE.
Ok - morning bloviation over.

Nobody asked Shawyer to prove anything as he should be wise enough to see it is clearly not his expertise field.

The resulting perception of such non-sense is one of charlatanism, which hurts a broader scientific interest in the EMdrive.
Even for a simple layman like me, with STEM college education and a MArch univ degree, I can't possibly understand that he, as a qualified engineer, can be satisfied with those ridiculously simplified answers.
It would be far better to let the results speak for themselves , instead of attempting to fabricate his own marketing material and communication strategies. In his specific case, it is horrendously contra-productive...

Agree. He doesn't have to explain how it works, just show that it works. That's actually my personal little grievance with him of late.
So far he has only provided visible proof of the first experiments with minute amounts of thrust. There are schematics, photos, even videos of them in action.
This is what made a few people interested enough in them to try a replication on their own.
But he has not provided a single shred of proof about his more outrageous claims of hyper-strong Emdrives since. No pictures of the working setup, no videos or tables of results. Nothing but some schematics and photos of presumed superconducting devices being prepared and a lot of promises and "breadcrumbs".
That is completely in contrast with what he did before, showing the meat of the stew: the devices assembled and working. Ergo, no evidence, just believe me something big is upcoming.
You see why many are upset and not willing to believe?
If it wasn't for the terrific people doing experiments and sharing their results in the open, this whole story would have ended for me long ago, and placed besides so many cranky claims made before.
But as a philosophical realist, I can't bury the findings of several independent people in the sand and be done with it. This has to be explained. Either as experimental error, but not just dismissed as such, but carefully explained why this error looks like thrust.
Or confirmed and then we can toll the bells and sing hallelujah. But not a second before. -

https://www.newscientist.com/data/images/ns/av/shawyertheory.pdf
Now, tell me how that is wrong.
First error is the original statement of force difference between the end plates ignoring the force on the sidewalls.
Next, he points to the Lorentz force equation and puts in the "group velocity of the EM wave" rather than "the velocity of the charged particle" which is the actual definition of v in that equation.
After that he makes a claim that special relativity magically makes it an open system. There is nothing in special relativity that supports this.

Even Dr. white's theory of Quantum Vacuum particles makes it outside the cavity and as does the MACH effects, or any theory that maybe causes a gravitational link or disturbance to the outside.
Anyone who says that they have a theory of just particles of light or matter that stay inside of the enclosed frame environment of the cavity bouncing around giving thrusts is going to get flack and questions asked in do they understand completely Maxwell's equations. Maxwell's equations for electromagnetism have been called the "second great unification in physics" and I don't believe Shawyer's theories trump them.

A micromechanical proof-of-principle experiment for measuring the gravitational force of milligram massesQuote
This paper addresses a simple question: how small can one make a
gravitational source mass and still detect its gravitational coupling to a nearby test
mass? We describe an experimental scheme based on micromechanical sensing to
observe gravity between milligram-scale source masses, thereby improving the current
smallest source mass values by three orders of magnitude and possibly even more.
We also discuss the implications of such measurements both for improved precision
measurements of Newton’s constant and for a new generation of experiments at the
interface between quantum physics and gravity.
....
For this reason, simply scaling down a Cavendish experiment is not sufficient
to measure the gravitational effects of small source masses.
Instead, we periodically modulate the gravitational potential created by a small
source mass in order to resonantly enhance the amplitude response of a cantilever test
mass.
‡ For simplicity we assume that the effective mass of the oscillator mode is identical to the gravitational
mass.
§ The frequency shifts in actual measurements of G are typically one order of magnitude higher, as
the geometry of a torsion balance pendulum is only vaguely approximated by our 1-dimensional, linear
model.

Now, tell me how that is wrong.
You should be really interested in Shawyer's work! There seems to be a general consensus here that Shawyer's theory as to how it works is flawed yet obviously, there is enough serious interest that the EMDrive may indeed work that many are pursuing builds and tests. But Shawyer's insights with microwave engineering led him to his concept and his equation. As a working equation, Shawyer's thrust equation seems also to have some predictive power even if the derivation is flawed, perhaps it's close to, or an approximation to the correct equation that could be derived from correct physics.
Remember that Shawyer is an engineer, not a theoretical physicist which may have allowed him the freedom to explore this concept without giving up first as theory might have convinced him the whole thing is impossible. In other words, he didn't outsmart himself. So, please take the criticism of Shawyer's theory paper in context. If it really works, he is the inventor of a device of major importance and that also will lead directly to a better understanding of physics.
