Hi,

You can set up the required phase delay without rotating the model in Ansys HFFS. Since you are using coupled boundaries you can set the required polarization. You need to enter the required polarization by setting 45 degrees next to the phi scan angle in the phase delay dialogue box. For detailed information, please read through - "Assigning Coupled Lattice Pair Boundaries" section in the HFSS Help pdf document. Alternatively, you can go through this link - Ansys Electronics 2022 R2 - Assigning Boundaries in HFSS in the online Help document.

You can also go through this free Ansys Innovation video course on using Floquet port - Ansys HFSS Floquet Port - ANSYS Innovation Courses which covers the same details.

Best regards,
Praneeth.
