Circular Polarization

 

the state of a propagating electromagnetic wave (such as a light wave) in which the end points of its electric and magnetic vectors E and H describe a circle in a plane perpendicular to the direction of propagation at every point in space occupied by the wave.

circular polarization

[′sər·kyə·lər ‚pō·lə·rə′zā·shən]
(physics)
Attribute of a transverse wave (either of electromagnetic radiation, or in an elastic medium) whose electric or displacement vector is of constant amplitude and, at a fixed point in space, rotates in a plane perpendicular to the propagation direction with constant angular velocity.
