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.

The decision to emphasize intermittent exposure and circular polarization was based on research indicating that such exposure is associated with alterations in human physiology (26-28), and also on rodent research reporting that circularly polarized fields are more effective than linearly polarized fields in reducing nocturnal melatonin levels (29).
