How to extract Lr, cl, LL, CR from a base 3D model of a leaky wave antenna?

for the leaky wave antenna i have calculated circuit Lr, cl, LL, CR values based on dispersion diagram and blochs diagram. I want to model a 3-d simulation based on these CRLH values.
I am having a hard time doing that.
It would be great of someone could assist me in how to extract Lr, cl, LL, CR from a base 3-d model I simulate. then I could use trial and error method to reach the values of my circuit model.
Thanks,

Hi，do you know the answers.I am also looking for the methods.Some one said that,first obtaing S parameter by simulating the CRLH antenna, then calculating the ABCD matrix through the S parameter,after getting the ABCD parameter,maybe it is more easier to extract L C．Also, I am not clear enough.

I too want to work with CLRH line but not sure how to calculate these network parameters.
