[SI-LIST] S-parameter to Circuit Model extraction?

 P{margin-top:2px;margin-bottom:2px;} 
Hello, 

  

I measured some PCB structures and Wafers by VNA to get the S-parameters. 

As I know, there are many extraction algorithm in this world, right? 

But I know only one technique which is EO's paper in 1992. 

If anyone knows other methodologies, please reply me. 

  

By the way, to compare the measured S-parameter with the simulated
S-parameter from circuit model, 

I think that I have to do spice simulation. But I am not sure the spice can
extract S-parameter from 

frequency dependant circuit models. 

And which circuit model is more accurate, for example PI-Model, T-Model,
Telegraph Equation.? 

  

Thank for your reading.
