i simulate a unit cell in cst and i want to plot its group delay? in hfss this item is ready. but i can't find this clearly in cst software.
Hi Azita
After simulation with more than 2 ports, you can do as follow:
1- go to: Post processing tab -> Template Based Post Processing.
2- In the opened window, select "،Time Signals" in the first drop-down menu.
3- Select "Group Delay Time" in the second drop-down menu.
4- Determine the receiver and transmitter ports as well as relevant modes.
5- After closing the window, click on "Evaluate" button.
Enjoy the result!!
hi dear amir
thank you for your answer. but it is't done and an error is occured. i think this delay group is not appropriate for unit cell. i want plot group velocity from s_parameter phase. in hfss, i do it with group delay in results, but in cst i think it is different.
Hi Azita,
Follow the Amir's steps (see above) but, if you are using "unit cell" boundaries, in the dialog box ("Group delay time") please insert
To Port: Zmax
To Mode: 2
From Port: Zmax
Form Mode: 1
In other words, you need to insert the right port name you are using and the right modes.
Best Regards,

@ Stylianos D. Assimonis But plot for ADS and HFSS Group delay is plotted Sdelay vs Frequency. But for CST time vs frequency.
How we can change in CST?
Sdelay vs Frequency in CST?
