I agree withShawyer and like the breach in isotropy created by
Casimir cavities it segregates vacuum density only the EM requires both power
and the trapezoid geometry to form the segregated regions which the rf also
pushes against in a manner biased in favor of one region over the other. IMHO
he might find more evidence if he did a beam balance measurement of
propellant–less braking while adding or subtracting weight from the counter
balance because he would be able to measure all the linkage to ether effects
differentially wrt the device turned off. My point is the EM drive still
suffers from the same weakness as the failed circa 2k DeForio et all experiment
with stacked parallel Casimir cavities in trying to establish a spatial bias,
If I am correct the motion of segregated vacuum density regions through the
macro isotropy is exactly equivalent to frame dragging in astrophysics with out
the need for relativistic velocities. The clues have been there, anomalous
spontaneous emission of photons in microwave cavities, anomalous half life
decays in nano powders – Puthoff coined the term vacuum engineering but few are
willing to believe negative vacuum density can be manipulated easily to
relativistic values in regions large enough to contain hydrogen gas and control
its decay rate thru time dilation.

A related but alternative bit of insight comes from John Wallace in the cited
paper on spin waves. I thought Bob Cook was aware of it, but maybe not since he
did not bring up the most important detail - mass.
It would be relevant to Shawyer’s drive if the Frustum were to have an iron
liner component, such as an inner layer of sheet iron or even iron plating,
which is not the case, but anyway this paper is worth a read on the off-chance
that copper can produce spin waves like iron (doubtful).
http://arxiv.org/abs/0901.1631
In Wallace’s hypothesis, applied to Sawyer, RF would be converted into
transverse (spin) waves. These waves have special properties and importantly
they have mass. One dispersion curve yielded a real but exceedingly small
effective mass of 1.8 10^{-39}kg for spin waves… which is not too far removed
from the mass energy of the microwave photon which created it. But unless the
copper frustum acts to release the same spin wave as does iron this explanation
does not work for Em. Plus, since these waves have mass, they can be depleted
over time without a replenishment source which spoils the idea of very long
space missions. Most of the idealists balk at a theory that doesn’t get them
access to intergalactic Sci-Fi missions. ☺
There are other partial explanations which actually mesh with spin waves.
Shawyer claims that a standing wave interference pattern is created by
geometry, operating frequency path lengths. And he claims that “stress energy
of space” is altered by the interference pattern. That sounds a lot like
aether. A chiral aether with effective mass, together with spin waves of
effective mass – that would explain everything - yet observers shy away. Too
bad.
A third slant is Puthoff's patent - showing that a small but detectable curl
free potential can be created from interference patterns passing through
barriers, presumably like a copper wall. If the microwaves remain inside the
cavity, then there is no interaction with the vacuum except by invoking a
massive wave, and consequently, there is no established theory to give external
thrust to the device except the Wallace approach, which comes the closest since
it predicts wave-particles of low-but-real mass. Wallace does have real
uncontested data for spin waves whereas Shawye’s data is challenged.

This is along the lines that I was thinking.
Consider a simple thought experiment. We have a microwave waveguide with the
output focused in a single direction sitting out in the middle of space where
there is little in the way of an external field. Attached to it is a battery
sufficient to drive a magnetron at 10 W for some period of time. We turn on
the magnetron remotely. Microwave photons with a total power amounting to 10 J
per second are now being emitted in a preferred direction. For the sake of
argument we will go with the well-accepted assumption that photons have no
mass. Nonetheless they have momentum, and in order for the system to conserve
momentum it will move in a direction opposite the majority of the photons.
We have yet not specified what the system is pushing off of, but I don't think
we need to in order for the thought experiment to work.
