Checkout emdrive.com for some of the theory and results. The inventor insists that no special physics is required to understand the experimental results. Basically Newton plus Special Theory of Relativity makes it happen he claims.
Instead, I'm wondering if this is actually confirmation of Wal Thornhill's suggestion that gravity is the result of an internal deformation of atoms creating small dipoles.
Could it be that the microwaves are deforming the copper atoms on the larger plate such that they are forming tiny dipoles where the negative side is pointing out and the positive side is pointing in the chamber?
If this were true then I should feel an attractive force when I place my hand behind a fixed super-conducting EmDrive that's turned on because the atoms in my hand along with the air molecules would synchronize with the induced dipoles of the chamber.
The EmDrive community is inventing all kinds of complex, wild physics to explain the experimental results. I'm wondering what the Electric Universe theory has to say about it.

The EmDrive is a fascinating anomaly. It consists of a truncated metal cone (cavity) with a magnetron inside that inputs EM radiation with the same wavelength as the size of the cavity (it's just like a loudspeaker-shaped microwave oven). It has been shown by three different groups (UK, China, US) that when a resonance is achieved the cavity moves slightly towards its narrow end in apparent violation of the conservation of momentum, since there is no expelled mass to cause this. There was a suspicion that the movement was due to air currents, but NASA have just this last week shown that the same thing happens in vacuo.

The produced micro-wave emission is tuned to resonate with the megaphone dimensions, increasing the Q factor and hence the amplitude of the emitted waveform.
I don't see where it could be a standing wave, like a vibrating guitar string producing a single standing sine wave, but perhaps i'm missing something in McCulloh's description.
In fact, it would seem to be a highly non-linear form, which having been harmonicly amplified, [similarly to light in a lasing crystal or resonant diode cavity], until it is emitted directionally by the cone.
At a macro scale, the the "cones' where propellent is ejected from a rocket engine creates a similar effect.
The interaction of 'wave phase" against sloping funnel shape, being the wave mechanics employed here.
To the hard question, ? what is the microwave emission acting against<> to produce thrust , Upriver's scenario ~reversed
seems plausible. The aetheric matrix can provide an inertial platform or backdrop, upon which the generated microwave radiation may push off (maybe also 'pull to' ? see 2-15-15 comment),
thus inducing motion.
"Dipole" generation can be used to describe practically any energetic transfer/transform in electrical terms, but here is likely a secondary or derivative effect, imo.

The thing is certainly reminiscent of the Casimir effect, for which one is also tempted to as "where is the reactive force??" However, "hubble scale casimir force".. c'mon really? I wouldn't expect this kind of appeal to cosmology to get much traction here.

I did say his ideas are bizarre - I'd say even weirder than the electric universe because you have to accept a holographic understanding of the universe. However, it is his results that make his work compelling. If it is complete nonsense how is he getting such good results? Perhaps he has the formula right by accident and is just trying to guess at how he got there.
McCulluch is pretty modest it sounds like, I think he is even surprised at his work himself. This is the little guy taking on the established view within its own traditions. I think an EU reader would find that they share his values and so find his work to be interesting.
How is this different than laser tweezers?

It is the opposite.
The tweezers Trap a particle between the 'hills and valleys' of constructively interfering wave forms, producing a "standing wave".
The EmDrive produces Thrust.

If this still isn't enough to chew on, remember that it isn't clear at all that there's a boundary of some sort 13B ly away.
