WebbThe Poincaré sphere is most useful for visualizing problems involving nonabsorbing materials, various polarization instruments including polarizers, retarders, … The Poincaré homology sphere (also known as Poincaré dodecahedral space) is a particular example of a homology sphere, first constructed by Henri Poincaré. Being a spherical 3-manifold, it is the only homology 3-sphere (besides the 3-sphere itself) with a finite fundamental group. Its fundamental group is known as the binary icosahedral group and has order 120. Since the fundamental group of the 3-sphere is trivial, this shows that there exist 3-manifolds with the sam…

Webb6 dec. 2024 · Metasurfaces have recently enacted diverse electromagnetic manipulations in polarization optics. However, they only support one or a few polarization functions in a single design. Here, an arbitrary and dynamic Poincaré sphere polarization converter to implement full-polarization optics with a single time-varying metasurface is demonstrated. http://www.map.mpim-bonn.mpg.de/Poincar%C3%A9%27s_homology_sphere WebbWith some work, one can give a general proof that the closure phase (phase of ) is equal to half the solid angle subtended at the centre of the Poincaré sphere by the points represented by , , and on the surface of the sphere. For the case where the polarization state of the three antennas are same, this phase is zero in general. martens and heads

WebbPoincaré's famous example of a non-simply connected 3-manifold with the same homology as the ordinary 3-sphere appeared in 1904 [14].

For historical reasons, in optics the Bloch sphere is also known as the Poincaré sphere and specifically represents different types of polarizations. Six common polarization types exist and are called Jones vectors.
