In [[Classical electromagnetism|electrodynamics]], '''circular polarization''' of an [[Electromagnetic radiation|electromagnetic wave]] is a [[Polarization (waves)|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.
