Hello, i am trying to understand the final part of the article shown in the link bellow.
Could you pease help me understand how from simulation you got the Z values in the table?
Is it from S-params?
I think R is S11 ,all the numbers in the impedance table are complex.
Do i put the complex part of the S11 inside the formula?

Hi,

yes, it is clearly mentioned that R is the reflection coefficient

"The input impedance of the structure can be
expressed in terms of the simulated reflection coefficient R as ..."

You have to use the complete reflection coefficient, not only its imaginary part.
