|Good point about the surface tension effect causing the conductive particles to be completely covered and surrounded...
And, any detuning effect is probably limited - can’t lower the resonant frequency of particles from GHz (?) to MHz...
How about capacitive coupling of one particle to the next? Capacitance has Area in the numerator and distance in the denominator... Probably not much there - the A is to small and the d too large. Hmm.
The effect cannot be zero . . . but it's
beyond my current understanding to assess
its significance. Plan B is an empirical
test. Got all the stuff laying around here
to do it . . . just no time at the moment
and besides, my 'antenna range' temperatures
are in the high 90's right now.
I need to identify all the 'suspect' paints
and get samples. Will test some 'aluminum'
off-the-shelf paints too.
