All, can you help me out with the relative magnetic permeability of a few
conductors?
I've spent most of the afternoon using google and searching through the
numerous engineering, physics & chemistry handbooks in our library, all to
no avail. I'm looking at materials used for MCM conductors plus a few others
for comparison, with a view to analysing the effects on multi-gigabit serial
link type signals.
Ideally, I'd like to complete the following list for relative magnetic
permeability, Ur:
copper, Ur = 1.
gold
molybdenum
tungsten
nickel, Ur in the range 5 to 20 (assume 10) at 1 GHz (see Johnson & Graham,
black magic 2, p267).
However, even if such figures are forthcoming, are they close enough to the
paste like compounds used for MCM conductors?
Cheers,
Mark.
