Hello Michael,
Mmmmm, I am responding to my own post. Go figure.
Thinking about my question of yesterday, I come to realize that of course
the dielectric constants would not be additive. They should be 1/(1/k1 +
1/k2).
But I am still interested in hearing what others' experiences have been
with paper. I just received a 74lb roll of polyethylene that is 20" wide
and 8mil.
Michael
