[[ja:直線偏光]]
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]] for more information.
Historically, the orientation of a polarized electromagnetic wave has been defined in the optical regime by the orientation of the electric vector, and in the [[radio]] regime, by the orientation of the magnetic vector.
