Is it possible to get a equivalent capacitance from S parameters?

[boladore]

Hi there,
first, I apologize for my poor English.

I made a simulation model and get results from HFSS

Model has a equivalent circuit like that.(1)
I run that model and get pair of solutions 'frequency vs response' like S parameter for each frequency.
So, with these results, is it possible to get (or calculate) a capacitance for whole circuit?(2)

My professor said, "Maybe you can get a capacitance from known values using ADS, but I can't not exactly say to you how to get a capacitance. but there may be another methods to do it."

regards

Look at the frequency response of the 5 parameter circuit. Does it look similat to a 1 parameter equivalent. If yes, you have your answer. If no, then it sounds not possible. Correct?
