Hi!
Actually, there are some ways to plot spectral responses, but I just present one of them.
First of all, you must define a port boundary condition where you are interested to get or inject output and input signals, respectively.
(Assume that incoming signals have been injected from port 1, and output signals received from port2)
After a multi-frequency simulation....
1) Go to "Derive Values" section under results and add "Global Evaluation" .
2) From the Data set list, in the settings window for "Global Evaluation" , select "Parametric Solutions".
3) In the Expression text field, choose S21 (from port branch found in module tree) and click the "Evaluate" button.
4) After evaluation, the results are resembled as Table.
5) Finally, In the settings window for "Tables" right click on table and select to plot.
thank you so much
excuse me
can you help me in the port setting for MDM waveguide?
what is the type of port for 2D structure? (rectangle, numeric, periodic,...)?
in user defined type, I select the electric field in the X cordinect but i see error!
please help me. thank you so much
Dear San
You have to use periodic port and flouqet boundary conditions
