Reply To: Magnetooptical materials , Polarisation Rotation

HI , Thanks.
I am able to see the rotation in the polarisation, this part is fine.
But i have a question.
first, i am going +z direction , and i have certain pol rotation in light after passing through the magnetooptical material. I can calculate that pol state using pol ellipse, as given here. https://support.lumerical.com/hc/en-us/articles/360034395234-Calculating-the-far-field-polarization-ellipse
Now, when i am going back (-z), why the polarisation is going back to its original state , i think it should further add polarisation ?
