EM drive just got peer reviews and it does not look good.
Unfortunately, a new round of research out of Germany is casting some big doubts on those early results. In a new research paper the team argues that not only does the engine not actually produce any thrust, but that earlier tests may have erroneously detected thrust due to “electromagnetic interaction” between the engine and Earth’s own magnetic field. Oops!

but if it works in orbit that still could be useful.

All that seems to ring true as well.

We will have to see what Woodward does to address it.

It might be a decent shot to try a different design, like the magnetic oscillator I've mentioned. While there is magnetic issues to be dealt with the cap stack could be on an air bearing or something and thus have no space for Dean drive effects in the piezo stack.

My google fu has been short on finding me maximum possible frequencies it could run at, and all I can remember from a community college class is it should be more than a few KHz.
