Hello asubraman,
Import or read your S-pareameter file to any simulator (AWR MWO or Sonnet EM)
then plot the Y parameters Then use the following equation to get the Capacitance & Indutance values
Y11 = Im(Y(1,1))
C1=1.0E12 / ( 2 * _PI * _FREQ * ( 1 / Y11 ) )
Where
L1=1.0E9 * ( 1 / Y11 ) / ( 2 * _PI * _FREQ )
L1: Effective Inductance (in nH) of a series RL network
C1: Effective Capacitance (in pF) of a series RC network
_FREQ: is project frequencies in GHz
Note: Sonnet has direct measurement option for the above...
