Query: Spin polarization separation of reflected light at Brewster angle   A novel spin polarization separation of reflected light is observed, when a
linearly polarized Gaussian beam impinges on an air-glass interface at Brewster
angle. In the far-field zone, spins of photons are oppositely polarized in two
regions along the direction perpendicular to incident plane. Spatial scale of
this polarization is related to optical properties of dielectric and can be
controlled by experimental configuration. We believe that this study benefits
the manipulation of spins of photons and the development of methods for
investigating optical properties of materials.
