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 square notches in the outer annular slot and the meandered slot section in the inner annular slot provide dual-sense circular polarization at the two frequencies by perturbing the symmetry of the annular slots in order to split the fundamental resonant mode into two orthogonal degenerate resonant modes, which lead to LHCP radiation in +z direction at 1.

They can also further customize the products to enhance the LCD output, provide custom enclosures or mountings and meet special optical requirements including using Fujitsu touch panel features such as high transparency and circular polarization.
3 percent) circular polarization in the maser signal.
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).
These spiral antennas are circularly polarized and can sense signals of all polarizations with varying sensitivity, except the opposite sensed circular polarization.
S = [+ or -] 1 corresponds to linear polarization; S = 0 corresponds to circular polarization.
