Feko reflectarray graph of reflection phase and amplitude vs. dipole lengths

Hello everyone! I am starting to use the Feko program and I have to make a unit cell of a reflectarray, where I can see the phase difference, and the amplitude versus the length of the dipoles by means of a parameter sweep. The only thing I can find right now are the reflection and transmission coefficients. I attach the model in case I am missing something.
Thank you very much in advance!
