How to create TE11 and TE21 with HFSS?

Hello HFSS Designers.

Do you know any exact method of creating TE11 and TE21 modes in a rectangular waveguide?

I ve designed for TE10 and TE20 and also TE00 with editing sources easily. Do i need to use integration line ? If yes, How?

For modes:

thanks for your help

Hi !
Yes ! It is simple, just define number of modes at the waveguide port greater than one (five for example) and look for port only solutions.
You will see the set of eigenwaves in increasing order of cutoff frequencies.
You can simplify this problem and calculate less modes if you will define proper boundary (perfect E or H plane) conditions.
