Of elliptically polarized incident @R05048@, these are given by \[s_{0}^{0}=E_{1}^{0}+E_{2}^{0}\] \[s_{1}^{0}=E_{1}^{0}- E_{2}^{0}\] \[s_{2}^{0}=2\ \sqrt{E_{1}^{0}\ E_{2}^{0}}\ \cos \delta ^{0}\] \[s_{3}^{0}=2\ \sqrt{E_{1}^{0}\ E_{2}^{0}}\ \sin \delta ^{0}\] where \(E_{1}^{0}\) and \(E_{2}^{0}\) specify the @I03254@ of the incident light polarized with their electric vectors vibrating perpendicular and parallel to the @S05493@, respectively and \(\delta ^{0}\) is the phase difference between these electric vectors.
