[SI-LIST] Flat Flex Cable Impedance

Hello,
I am working on a project that involves a flat flex cable interconnect and
would like to know how to calculate the impedance of the cable. I have
taken
a look at Howard Johnson's "A Handbook of Black Magic" but am failing to
see any specific reference to calculating impedance for this type of flat
conductor
(edge coupled) interconnect, although I would not be the least surprised
if I
have missed something. The book does have a great reference to ribbon
cables
and from that I am under the assumption that I need a GND SIG GND trace
pattern,
but would still like to doublecheck what this is going to give me for a
cable impedance.
Can anyone that uses flat flex regularly give me any help?
Thanks,
Chris
