Of elliptically polarized incident @[email protected], 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 @[email protected] of the incident light polarized with their electric vectors vibrating perpendicular and parallel to the @[email protected], respectively and $$\delta ^{0}$$ is the phase difference between these electric vectors.
