Adrianus,

I have worked with ATN Microwave, Inc. in Boston (acquired last week by
Agilent) in extracting RLGC from s-parameters. I my case, I was using
differential s-parameters, so the matrix was 4 x 4, not 2 x 2. ATN has a
software package that does this that is based on the following reference:

W. Eisenstadt and Y. Eo, "S-parameter-based IC interconnect transmission
line characterization," IEEE Transactions on Component, Hybrids and
Manufacturing Technology, Vol. 15, No 4, August 1992, pp. 483-490.

I can give you a contact at ATN, if you wish.

Jim

                 << File: Adrianus Djohan.vcf >> Hi,

                I'm wondering if anyone has success with finding an
equivalent RLGC element
                for a set of s parameters. For example: Given a set of S
parameter as a
                function of frequency (2 by 2 by f) as typically one would
get from a
                network analyzer. What would be the method to compute an
equivalent RLGC
                element for each frequency, assuming that the RLGC element
is 1/nth of the s
                parameters?

                THanks,
                Adrianus
