axis of polarization
41Optical axis gratings — (OAGs) are gratings of optical axis of a birefringent material. In OAGs, the birefringence of the material is constant, while the direction of optical axis is periodically modulated in a fixed direction. In this way they are different from the… …

44Optic axis of a crystal — For the axis of an optical system, see Optical axis. The optic axis of a crystal is the direction in which a ray of transmitted light suffers no birefringence (double refraction). Due to the internal structure of the crystal (the specific… …
45Circular polarization of starlight — The circular polarization of starlight has been observed to be a function of the linear polarization of starlight.Starlight becomes partially linearly polarized by scattering from elongated interstellar dust grains whose long axes tend to be… …
46Linear polarization — In electrodynamics, linear polarization or plane polarization of electromagnetic radiation is a confinement of the electric field vector or magnetic field vector to a given plane along the direction of propagation. See polarization for more… …
47Cham Albanian collaboration with the Axis — During the Axis occupation of Greece between 1941 and 1944, large parts of the Albanian minority in the Thesprotia prefecture in Epirus, northwestern Greece, known as Chams (Albanian: Çamë, Greek: Τσάμηδες, Tsamides) collaborated with the… …
