Folks,
I've got a question. Is this definition correct?
[tex]\delta _i = \frac{2\pi}{\lambda_i} * n_i * \cos \, \theta _i[/tex]
where
[tex]\delta _i[/tex] is the optical thickness of medium [tex]i[/tex]
[tex]\lambda _i[/tex] is the wavelength in medium [tex]i[/tex] (i.e. not [tex]\lambda _0[/tex], the vacuum wavelength)
[tex]n_i[/tex] is the refractive index of medium [tex]i[/tex]
[tex] \theta _i [/tex] is the angle with respect to the normal inside medium [tex]i[/tex]
