Circular polarization

In electrodynamics, circular polarization of electromagnetic radiation is polarization such that the tip of the electric field vector at a fixed point in space describes a circle. The magnitude of the electric field vector is constant.

A circularly polarized wave may be resolved into two linearly polarized waves, of equal amplitude, in phase quadrature and with their planes of polarization at right angles to each other.

Circular polarization may be referred to as "right-hand" or "left-hand," depending on the direction in which the electric field vector rotates.

See polarization for more information.
