I would like to have a clear and consise definition for the term
"permittivity" as it relates to dielectric materials.  I have
read no less than fifty different definitions and descriptions
and still do not have a clear and consise definition.  In
several of the references, it simply states, ...see dielectric
constant.  However, the other descriptions and definitions of
permittivity lead me to believe there is a subtle difference
between the two terms.  The definitions for relative dielctric
constant are fairly clear and consistent between the various
references I have used, but the definitions for permittivity are
ambiguous and inconsistent.

For the best definition, I will send the dude or dudette a
nice bottle of California White Zinfandel
