Polarization density - Wikipedia
In classical electromagnetism, polarization density (or electric polarization, or simply polarization) is the vector field that expresses the volumetric density of permanent or induced electric dipole moments in a dielectric material.
Electric polarization | Definition, Units, Example, & Facts
Polarization occurs when an electric field distorts the negative cloud of electrons around positive atomic nuclei in a direction opposite the field. This slight separation of charge makes one side of the atom somewhat positive and the opposite side somewhat negative.

Polarization is the attribute that wave oscillations have a definite direction relative to the direction of propagation of the wave. EM waves are transverse waves that may be polarized. The direction of polarization is defined to be the direction parallel to the electric field of the EM wave.
What is Electric Polarization and How Does It Affect Our Daily …
2021年8月18日 · Polarization density (also known as “electric polarization,” or simply just “polarization”) decides the response of an object towards an electric field. It is also responsible for the changes...
Electric Polarization - Definition, Unit, Dimension, and FAQs
The electrical polarization occurs when, because of the electric field, the negative electrons are pushed towards the positive atom nuclei surrounding it. This distortion of charges results in one side of the atom becoming a little negative and the opposite side becoming a little positive.

2024年1月14日 · Electric polarization is a slight relative shift of positive and negative electric charge in opposite directions within atoms or molecules of an insulator, or dielectric, induced by an external electric field.
33 Polarization - The Feynman Lectures on Physics
When the end of the electric field vector travels around a circle, we have circular polarization. If the end of the electric vector, when we look at it as the light comes straight toward us, goes around in a counterclockwise direction, we call it right-hand circular polarization.
3.7: Polarization - Physics LibreTexts
There is an important principle in physics that states that the conditions at the boundary have to work out properly. This means that the electric field vector of the incoming light must add up properly to the electric field after striking the interface.
5.17: Polarization and Susceptibility - Physics LibreTexts
When an insulating material is placed in an electric field, it becomes polarized, either by rotation of molecules with pre-existing dipole moments or by induction of dipole moments in the individual molecules. Inside the material, \(D\) is then greater than \(\epsilon_0 E\).
