I have been trying to find the phase difference to test whether polarization is converted or not in a metamaterial polarization converter. But I am not sure how to do that.
In the below paper, how did the authors got the graph in Figure-3.
We are using floquet port. We used one method where we go to "floquet boundaries' and then tick the box "polarization independent of scan angle phi" and put +45 once and then -45. we then took the S11 of the two simulations (+45 and -45) and then subtracted the phase of these two.

P.S.- I have attached some screenshots of the changes we did to the floquet boundaries. The last image is the phase difference I got following this method. It matches the figure slightly, but I am confused whether my method is correct or not.
Any help is appreciated.
-45 ve +45 derecede oluşturulan faz farkı 90 derecelik faz farkına eşit olur. Aynı şekilde +90 derecelik faz farkına karşılık - 90 derecelik farkına sahip olur. Aynı durum - 90 derece için geçerli. - - 90 ve +90 derecelik faz farkı +180 ve - 180 derecelik faz oluşturur. Grafik simetrik ve iki tarafı eşittir. Bunun için yapılan işlem doğrudur.
