Kapil Gavali

Using macros is the easiest way to plot interaction impedance vs frequency in CST studio. Go to Home->Macros-> Solver->E-solver->slow wave user defined watch. Set the boundary conditions as periodic for Z axis and simulate. You will get your plot along with dispersion diagram, normalised phase velocity, normalised group velocity, and E-axis amplitude.

Can you tell me how to plot the interaction impedance vs frequency graph using HFSS?

Dr-M. A. Ansari

Thank you! Kapil Gavali

Sorry, I am not using HFSS so I don't know much about that.

Dr-M. A. Ansari , any idea about interaction impedance using MAGIC?
