Hello,
I am trying to figure out how the electric field changes before and after passing through a waveplate but my notes don't make any sense.
I think
Eextin=Ecos[tex]\theta[/tex] and Eordin=Esin[tex]\theta[/tex]
where theta is the angle the electric field makes with the optic axis.
I can't tell how the amplitude changes on Eout though.
I know they pick up a relative phase but I can't tell if this is in addition to a phase anyway.
i.e is it just
Eextin=Ecos[tex]\theta[/tex]
and Eordin=Esin[tex]\theta[/tex] ei[tex]\Delta\varphi[/tex]
or if it should be the same but with a different amplitude i.e E' not E afterwards (in which case how do I calculate this?) or whether it should be
Eextout=Ecos[tex]\theta[/tex]ei[tex]\varphi[/tex]e
and Eordout=Esin[tex]\theta[/tex] ei[tex]\varphi[/tex]oei[tex]\Delta\varphi[/tex]
Or should it be this with E' instead of E?
This is what my notes suggest but I am hoping it is wrong since delta phi is [tex]\pi[/tex] so it would make it easier if it wasn't.
Thanks for any help.
