Here is Wikipedias definition:
In electrodynamics, circular polarization of an electromagnetic wave is a polarization where the tip of the electric field vector, at a fixed point in space, describes a circle as time progresses. If the wave is frozen in time the electric field vectors describe a helix along the direction of propagation. Circular polarization is a limiting case of the more general condition of elliptical polarization.

What is the definition of the term circiut?
There is no definition of the word "circiut" however the word "circuit" means a circular loop with a starting point and an ending point. Some synonyms include: round, circle, circumference.
What is the term for using a word in its own definition?
The term for using a word in its own definition is "circular definition" or "circular reasoning." This occurs when the definition of a word includes the word itself, creating a logical fallacy. It is considered a poor practice in formal language and logic as it does not provide a clear understanding of the term being defined.
What are the differences between linear and circular polarization?
Linear polarization refers to light waves that vibrate in a single plane, while circular polarization involves light waves that rotate in a circular motion. Linear polarization has a fixed orientation, while circular polarization has a continuously changing orientation.
What are the differences between circular and linear polarization?
Circular polarization and linear polarization are two different ways in which electromagnetic waves can oscillate. In linear polarization, the electric field of the wave oscillates in a straight line, while in circular polarization, the electric field rotates in a circular motion. This results in different orientations of the wave's electric field, which can affect how the wave interacts with materials and devices.

What is the polarization of the beam immediately following the quarter-wave plate?
The polarization of the beam immediately following the quarter-wave plate is circular polarization.
Explain the states of polarization?
The vibration of the electric field in radiation is perpendicular to the direction of the wave. This provides 360 degrees of for the vibration to occur in. Polarization is the angle of the 360 degrees that vibration occurs at. If the ligth is coming at yu like the face of a clock, the angle could be at 3:00, 6:00 or 9:00 or any angle. Some crystals rotate the angle of polarization, that is light goes in at 3:00 and comes out at 5:00. Normally reflection by a surface will absorb polarization not parallel to the surface, leaving the wve polarized parallel to the surface.
What is the direction of polarization?
The direction of polarization refers to the orientation of the electric field in an electromagnetic wave. It can be vertical, horizontal, diagonal, circular, or elliptical, depending on how the wave vibrates in relation to its direction of propagation.
Does plane polarization occur in a transverse waves?
Yes, plane polarization occurs in transverse waves. In transverse waves, the oscillations of the wave propagate perpendicular to the direction of the wave's travel. This allows the wave to exhibit different types of polarization, such as linear, circular, or elliptical polarization.
What is polarization of waves?
Polarization of waves refers to the orientation of the oscillations of a wave as it travels through space. Waves can be polarized in various ways, such as linear, circular, or elliptical polarization. Polarization is important in many applications, such as in telecommunications, where it affects the transmission and reception of signals.
What is cross-polarization?
AnswerIn RF communications, there are basically 3 common polarizations. They are horizontal polarization, vertical polarization, and circular polarization. Use the link below on antenna theory and see some examples and gather more information.Basically, polarization describes how the E-field is moving when it leaves the antenna.In horizontal polarization the signal moves in a horizontal fashion (-).In vertical polarization the signal moves in a vertical fashion (|).In circular polarization the signal moves in a circular fashion (O) with either left-handed or right-handed rotation.Now, when you want to talk to someone using horizontal or vertical polarization you want to match their angle of polarization exactly for the strongest signal.Cross-polarization is radiation orthogonal to the desired polarization. For instance, the cross-polarization of a vertically polarized antenna is the horizontally polarized fields.This is important to know because when you are setting up something like a satellite connection. In order to allow more signals through the satellite transponder within a fixed bandwidth and with decreased interference, the satellite makers alternate the polarization between adjacent transponder channels. (-|-|-|-|-|-|). Two adjacent channels can be "shoved right up against each other" and will interfere in a minimal way if they are polarized oppositely. Since interference affects their customers, satellite vendors are very touchy about proper polarization, and monitor gaps, called "guard bands" to ensure that you are properly aligned.

Why circular polarisation is not used for mw sdh or mw pdh radio backbone transmission link?
Linear vertical or horizontal polarization is normally used in microwave transmission. Reasons: Circularly polarized antennas are more complex and more expensive, because they are actually double polarized antennas, i.e. a combination of horizontal and vertical polarizations. Rain attenuation is lowest when the polarization is vertical. Therefore longer hops can be built if circular polarization is avoided.
What is co-polarization?
Analysis of circular polarization (CP) utilizes two independent, orthogonal, components: right- and left-hand circular (RHC and LHC). The desirable component, having the intended sence of rotation (right, or left), is called the copolarization component. The undesirable component, with the opposite polarization, is called the crosspolarization component. The mix of copolarization and crosspolarization components determine the quality of CP and correlates with the axial ratio.
