Hi Oliver,

Thank you for reaching out and your patience is much appreciated.

The scan angles for a coupled or lattice pair can be used to calculate the phase delay between the electric field at the primary boundary to the secondary boundary. Please go through this link - Ansys Electronics 2023 R1 - Assigning Boundaries in HFSS for detailed information on the same.

Best regards,
Praneeth.
