  2. Polarization identity - Wikipedia

    en.wikipedia.org/wiki/Polarization_identity

    Polarization identity. In linear algebra, a branch of mathematics, the polarization identity is any one of a family of formulas that express the inner product of two vectors in terms of the norm of a normed vector space. If a norm arises from an inner product then the polarization identity can be used to express this inner product entirely in ...

  3. Polarization of an algebraic form - Wikipedia

    en.wikipedia.org/wiki/Polarization_of_an...

    Polarization of an algebraic form. In mathematics, in particular in algebra, polarization is a technique for expressing a homogeneous polynomial in a simpler fashion by adjoining more variables. Specifically, given a homogeneous polynomial, polarization produces a unique symmetric multilinear form from which the original polynomial can be ...

  4. Polarization (waves) - Wikipedia

    en.wikipedia.org/wiki/Polarization_(waves)

    Polarization (also polarisation) is a property of transverse waves which specifies the geometrical orientation of the oscillations. [1][2][3][4][5] In a transverse wave, the direction of the oscillation is perpendicular to the direction of motion of the wave. [4] A simple example of a polarized transverse wave is vibrations traveling along a ...

  5. Stokes parameters - Wikipedia

    en.wikipedia.org/wiki/Stokes_parameters

    The Stokes I, Q, U and V parameters. The Stokes parameters are a set of values that describe the polarization state of electromagnetic radiation.They were defined by George Gabriel Stokes in 1852, [1] [2] as a mathematically convenient alternative to the more common description of incoherent or partially polarized radiation in terms of its total intensity (I), (fractional) degree of ...

  6. Jones calculus - Wikipedia

    en.wikipedia.org/wiki/Jones_calculus

    In optics, polarized light can be described using the Jones calculus, [1] invented by R. C. Jones in 1941. Polarized light is represented by a Jones vector, and linear optical elements are represented by Jones matrices. When light crosses an optical element the resulting polarization of the emerging light is found by taking the product of the ...

  7. Brewster's angle - Wikipedia

    en.wikipedia.org/wiki/Brewster's_angle

    Brewster's angle (also known as the polarization angle) is an angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no reflection. When unpolarized light is incident at this angle, the light that is reflected from the surface is therefore perfectly polarized.

  8. Fresnel equations - Wikipedia

    en.wikipedia.org/wiki/Fresnel_equations

    Fresnel equations. Partial transmission and reflection of a pulse travelling from a low to a high refractive index medium. At near-grazing incidence, media interfaces appear mirror-like especially due to reflection of the s polarization, despite being poor reflectors at normal incidence. Polarized sunglasses block the s polarization, greatly ...

  9. Circular polarization - Wikipedia

    en.wikipedia.org/wiki/Circular_polarization

    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. In electrodynamics, the strength and direction of an electric field is ...
