Here is my situation:
According to ellipsometry theory the complex reflectance ratio can be expressed as
[PLAIN]http://img255.imageshack.us/img255/2657/68578079.png
where tan([tex]\Psi[/tex]) is the amplitude ratio upon reflection and [tex]\Delta[/tex] is a phase shift.
On the other hand, as far as I now, phase shift upon reflection is [tex]\pi[/tex] or 0, depending on materials.
the question: is the [tex]\Psi[/tex] only variable that is being changed in wide range while [tex]\Delta[/tex] is either [tex]\pi[/tex] or 0 in all cases.
Sorry for not following subforum format, I just could not fit my question in it.
