Polarization is an important parameter in areas of science dealing with transverse waves, such as optics, seismology, radio, and microwaves. Especially impacted are technologies such as lasers, wireless and optical fiber telecommunications, and radar.
Depolarization is essential to the function of many cells, communication between cells, and the overall physiology of an organism. Action potential in a neuron, showing depolarization, in which the cell's internal charge becomes less negative (more positive), and repolarization, where the internal charge returns to a more negative value.
Its input polarization must be linear. Resulting output polarization is rotating linear polarization. Likewise, circular polarization can be depolarized with a rotating quarterwave plate. Output polarization is again linear. If a halfwave and a quarterwave plate are concatenated and rotate at different speeds, any input polarization is depolarized.
Photon polarization, the mathematical link between wave polarization and spin polarization; Vacuum polarization, a process in which a background electromagnetic field produces virtual electron-positron pairs; Polarization (cosmology), mechanisms for detecting astronomical polarization and the possible natural origins
In electrodynamics, circular polarization of an electromagnetic wave is a polarization state in which, at each point, the electromagnetic field of the wave has a constant magnitude and is rotating at a constant rate in a plane perpendicular to the direction of the wave.
The overlap between any two polarization states is dependent solely on the distance between their locations along the sphere. This property, which can only be true when pure polarization states are mapped onto a sphere, is the motivation for the invention of the Poincaré sphere and the use of Stokes parameters, which are thus plotted on (or ...
More women between ages 25 to 44 aren’t having children, for a number of reasons. But an article in The New York Times about the “unspoken grief” of never becoming a grandparent has gone viral.
Here the orientation of polarization is defined as the difference in azimuth between the observed pointing and the solar azimuth. The angle of polarization (or polarization angle) is defined as the relative angle between a vector tangent to the meridian of the observed point, and an angle perpendicular to the scattering plane.
