What is the difference between extracting (permittivity and permeability) by CST and by MATLAB code?

and how could I get negative value of the real part of epsilon and mu ?

Now they are near zero at resonant frequency(using CST).

Thanks for response.

Both tools uses mathematical formula based on the S-parameters.

CST - Equation can be defined (I am not sure in CST but possible in HFSS)

MATLAB - Equation based algorithm.

So, there will not be any difference as per my understanding.

Negative values are possible for meta materials.

Please check the literature of the same.
