[SOLVED] Simulate filter using CST

[pui]

How can I simulate coupling coefficient between 2 resonators using C*ST m*crowave s*udio, which one that can monitor (farfield, probes, discrete port or something)
And which tools using (transient, frequency domain or eigenmode)
I need your help
Best regard,

You must use only eigenmode's method.
The attachment's article will help you. Here is example at HFSS , but for CST all the same.

Good luck!

First you should get the resonant frequencies of odd and even models by Eigenmode soler.Then the coupling coefficients is k=abs(fe*fe-fo*fo)/(fe*fe+fo*fo).
