Alternate Titles: electron polarization, electronic polarization. Electric polarization, slight relative shift of positive and negative electric charge in opposite directions within an insulator, or dielectric, induced by an external electric field.
Polarization (also polarisation) is a property of some types of waves. Some waves have motion in another direction as well as the direction of the wave.In water, for instance, the wave will move across the water, but something on the surface of the water will move up and down.f both the electric field and magnetic field are perpendicular to the direction of the wave, the wave is called TEM (transverse electromagnetic). Linear, circular, and elliptical polarizations are specific cases of TEM polarization.
