Early quests for the EMdrive were of a cylindrical cavity
filled with a dielectric coating.

What does it mean when the asymetric EMdrive cavity is a form
of "attenuator also?


Is that supposed to make sense?


Maybe think of the general cavity as containing standing waves.
And some form of waves as causing the noted force? Tuning the power frequency to maximize the percentage of power as standing wave
is a cavity geometry affair.


Standing waves exert no force. That's why they're 'standing'.


Power supply interaction with the Earth's magnetic field
certainly needs addressing. See if it will rotate about
like a Ferris wheel. Does the vertical magnetic field vector
alter the performance?


Again I find myself wondering if this is supposed to make sense.


Also why not short the waveguide to look for power supply
effect?


Shorting waveguides tends to make them melt and explode.
