Information about Polarization (disambiguation)

Polarization or polarisation can mean:

polarization (Brit., polarisation) is the property of electromagnetic waves, such as light, that describes the direction of the transverse electric field. More generally, the polarization of a transverse wave describes the direction of oscillation in the plane

In classical electromagnetism, the polarization density (or electric polarization, or simply polarization) is the vector field that expresses the density of permanent or induced electric dipole moments in a dielectric material.

Abelian variety is a projective algebraic variety that is at the same time an algebraic group, i.e., has a group law that can be defined by regular functions. Abelian varieties are at the same time among the most studied objects in algebraic geometry and indispensable tools for

This identity is analogous to the formula for the square of a binomial:


If y in equation (1) is replaced by −y the result is

In politics, polarization is the process by which the public opinion divides and goes to the extremes. It can also refer to when the extreme factions of a political party gain dominance in a party. In either case moderate voices often find that they have lost power.

In communications and psychology, polarization is the process whereby a social or political group is divided into two opposing sub-groups with fewer and fewer members of the group remaining neutral or holding an intermediate position.

Racial polarization is the process whereby a population, the individuals of which have varying degrees of diversity in their ancestry, is divided into separate, and distinct (from each other) racial groups.

An example is the case of the demographics of Bermuda.

A polarizer is a device that converts an unpolarized or mixed-polarization beam of electromagnetic waves (e.g., light) into a beam with a single polarization state (usually, a single linear polarization).

Polarization is an important phenomenon in astronomy. The polarization of starlight was first observed by the astronomers William Hiltner and John S. Hall in 1949. Subsequently, Jesse Greenstein and Leverett Davis, Jr.
