I found the bit I was looking for, on first mention of this technology a few breads back I thought it reminded me of something

>[0008]… Their research involves the use of high Radio frequency/Microwave driven resonant cavity Q-thruster technology within the context of Quantum Vacuum Plasma physics.

and the use of

(from the description)

> the shell having embedded polycrystalline ferroelectric ceramic material, the material being polarized such that the ceramic material exhibits strong Piezoelectric Effect properties thus inducing high frequency vibrations;

barium titanate used as a dielectric in other experiments

>barium titanate ceramic dielectric

not sure if that's what is used, I just remembered it as a piezoelectric dielectric material that might fit. not sure it could be characterized as ferroelectric tho…

I just know it had interesting properties when polarized correctly and as a dielectric

>I don't see any special relationship between the use of Q (quality factor) in these patents and the individual(s) we talk to here who are referred to as "Q".

there isn't, or wasn't in my mind anyhow anything beyond the serendipitous fact that a novel form of space propulsion using microwave resonant cavities happened to be named after that Quality factor Q used to describe how efficient a component is at resonating.

the al__q__ubierre drive is another such happenstance occurrence in the field of space travel

have no fear, I don't think there's anything deeper in it other that random chance

I'm a student of the natural world and engineering in particular electrical engineering / phenomena have always interested me
