Polarizers which maintain the same axes of polarization with varying angles of incidence [clarification needed] are often called [citation needed] Cartesian polarizers, since the polarization vectors can be described with simple Cartesian coordinates (for example, horizontal vs. vertical) independent from the orientation of the polarizer surface.
Malus is probably best remembered for Malus's law, giving the resultant intensity, when a polariser is placed in the path of an incident beam. A follower of Laplace, both his statement of the Malus's law and his earlier works on polarisation and birefringence were formulated using the corpuscular theory of light. [1]
Fresnel's "plane of polarization", traditionally used in optics, is the plane containing the magnetic vectors (B & H) and the wave-normal. Malus's original "plane of polarization" was the plane containing the magnetic vectors and the ray. (In an isotropic medium, θ = 0 and Malus's plane merges with Fresnel's.)
The electron mean-free-path which governs this process is much smaller than the photon mean-free-path. Thus, the free electrons are tied to the radiation till a redshift of 20 or so. In other words, the small number of electrons have many collisions with a small number of photons, though most of the photons are unaffected.
The Jones vector describes the polarization of light in free space or another homogeneous isotropic non-attenuating medium, where the light can be properly described as transverse waves. Suppose that a monochromatic plane wave of light is travelling in the positive z -direction, with angular frequency ω and wave vector k = (0,0, k ), where the ...

1808 – Étienne-Louis Malus discovers polarization by reflection; 1809 – Étienne-Louis Malus publishes the law of Malus which predicts the light intensity transmitted by two polarizing sheets [citation needed] 1809 – Humphry Davy first publicly demonstrates the electric arc light.
In a year best summed up by “polarization,” the dictionary publisher fittingly also put the spotlight back on its inaugural Word of the Year for 2003, when it began participating in the annual ...
