Avner,
You'll have to supply more information. It's unclear what
you're really after. The Dielectric Constant of a material
is "constant" for the most part at the frequency of concern.
Depending upon alot of other factors, like the frequency
you're working at versus how the dielectric was tested, you
could get different values. Dielectric material has a
mathematical "complex" side to it. Enough!
It sounds like you're working some sort of calculation for
microstrip, buried microstrip, or stripline constructions
and getting different values for dielectricity. That by
itself is NOT good.
More info?

I like to know if anyone found that Dielectric Constant, for the same
material (e.g. FR-4),
might be different when used for calculation of Microstrip or for
calculation of Stripline.
