In both software you have to apply Floquet boundaries at least quarter wavelength apart from the radiating surface. In HFSS, after defining floquet boundaries, you have to use mode table calculator to consider enough modes for your geometry for the simulation. In general it depends on relative to highest frequency and to the hugest scan angles of your geometry. In CST, after defining unit cell you will see *Floquet boundaries*. Click on that, then you will see Floquet modes. From their based on your geometry select enough number of Floquet modes and run the simulation. Hope these will help. If its still not clear to you search in the internet for the following pdf document . * Getting Started with HFSS : Floquet Ports * . It will help you to better understand the TE and TM modes.
I hope this document will be helpful for TE &TM modes simulation with HFSS software.
The pdf of the gentleman Fathi Bendelala is very interesting, thank's for him !
Dear many experts
My concern is that how can I apply TE and TM mode in CST for the time domain (Transient Solver)? because I would like to check the result in the Frequency domain.
Please help and guide me on how to configure the TE and TM mode. How about the boundaries condition in order to change the phase shift?
Thank you very much for all helps

Dear all,
Thanks for your help.
I found also this file (attachment) which i think it will be helpful for every one.
How can I show a schematic of two modes (TE and TM) in CST?
The structure I am designing is a transmit array antenna. I intend to excite it with a linearly polarized wave and obtain circularly polarized output. For the simulation in CST, I have excited my unit cell with two Floquet modes, TE and TM, to model the radiation of a linearly polarized wave. Subsequently, I developed separate circuit models for the structure corresponding to the TE and TM excitations.
To model the general state, when both TE and TM modes are active in CST, I need to connect these two equivalent circuit models properly. This will allow me to achieve the overall equivalent circuit representation for the simultaneous excitation of TE and TM modes.
