Greetings, I want to realize the equivalent circuit for metamaterial unit element in ADS. But, the scattering parameter extracted for the same in CST is realized using boundary condition where the propagation vector is not normal to the plane of MM unit element. In such case, does there any relation between port positioning of MM UE (equivalent circuit realization) in ADS with that of the boundary condition defined in CST. If so by what way?? and how can i decide it.
