In [[electrodynamics]], '''linear polarization''' or '''plane polarization''' of [[electromagnetic radiation]] is a confinement of the [[electric field]] vector or [[magnetic field]] vector to a given plane along the direction of propagation. See [[Polarization (waves)|polarization]] for more information.

Historically, theThe orientation of a linearly polarized electromagnetic wave has beenis defined in the optical regime by the orientationdirection of the [[electric vector, and in the [[radiofield]] regimevector.<ref name="Shapira,">{{cite bybook the orientation of the magnetic vector.
