Hi dear friend ,
I'm trying to simulate coupling between two resonators.
but I dont know how to do this by using HFSS and extract coupling diagrams via eigen mode solver of HFSS.
can u help me please?
best regards
 

I don't think you can evaluate the coupling between two resonators using the eigenmode solution type. You need to switch to driven mode and check parameters which characterize the coupling effect (e.g., S12).
 

You can calculate the coupling coefficient using the following formula: k=(f2-f1)/sqrt(f1*f2), where f1 and f2 are eigenfrequencies.
What is coupling diagram?
 

You can calculate the coupling coefficient using the following formula: k=(f2-f1)/sqrt(f1*f2), where f1 and f2 are eigenfrequencies.
This is true only and only the Resonators are NOT coupled yet ( standalone ), Coupled Resonators will interact each other and Eigen Frequencies will be impacted.
The best method is to place 2-Ports and simulate them together like a Transformer.
