Differentiating Floquet modes in the PBC analysis

Hello,

I would like to know if there is a way to observe Floquet modes in the PBC analysis. In the other EM simulation tools such as CST or Ansys HFSS, the reflection and transmission responses of propagating modes can be obtained.

The figure below is the reflection coefficient of Jerusalem Cross element as given in the example guide, but illuminated by oblique incidence of theta=30 degrees. When the same problem is solved with other EM tools, the figure below corresponds to reflection response of TM00 mode, whereas the response for TE00 mode is very similar to its reflection coefficient under normal incidence. Is there a way to observe them in FEKO?

    Unfortunately Floquet modes cannot currently be visualized with Feko.
