A wave is polarised when all the vibrations are absorbed except those in one plane
Linear polarisation is the basic form and is usually termed Horizontal (HP) or Vertical Polarisation (VP) to describe the direction of the electric field in the plane at right angles to the direction of propagation
The locus or path described by the electric field vector of an electromagnetic wave, with respect to time See Polarisation summary
Direction of die electrical field vector of radiated radar energy with respect to a plane tangential to the earth (horizontal, vertical, left-hand circular, right-hand circular, elliptical, etc )

UK, alternative spelling of polarization
{i} making polarized, giving two opposite tendencies; condition of having polariy; phenomenon in which light waves move in one plane (also polarization)
The phenomenon in which radio waves are restricted to certain directions of electrical and magnetic field variations, where these directions are perpendicular to the direction of wave travel By convention, the polarisation of a radio wave is defined by the direction of the electric field vector Four senses of polarisation are used in satellite transmissions: horizontal (X) linear polarisation, vertical (Y) linear polarisation, right-hand circular polarisation and left-hand circular polarisation
the phenomenon in which waves of light or other radiation are restricted in direction of vibration
the condition of having or giving polarity
In an ionised medium in the presence of a magnetic field, a radio wave is split into two circularly polarised components, each propagating independently In the ionosphere a radio wave is split by the earth's magnetic field into ordinary (o) and extra-ordinary (x) waves The partitioning of the wave energy between the two depends on the angle the wave makes with the magnetic field At low frequencies, the x-wave is heavily attenuated relative to the o-wave

polarization
One frequency can be used for both sending and receiving data if the signals are polarized correctly Since signals are analogue waves they act like light waves Polarization of light, for example in sunglasses, removes all but one orientation of waves, so that say only vertical waves could be received In telecommunications polarization works the same way To communicate two independent signals on one frequency, the signals are cross-polarized This means that they are polarized at right angles to one another There are two types of polarization common in telecommunications: Linear and Circular Linear polarization is used for Ku-Band signals, and Circular is used for C-Band Polarizing the radio signals allows the same frequency to be used twice over the same coverage area while enabling the Earth Stations and the Satellites to discriminate between the two signals This effectively doubles the amount of usable bandwidth, i e capacity, available
polarization
The act of polarizing; the state of being polarized, or of having polarity
polarization
The direction of the electric field (E-field) vector of an electromagnetic (EM) wave See Polarization section The most general case is elliptical polarization with all others being special cases The E-field of an EM wave radiating from a vertically mounted dipole antenna will be vertical and the wave is said to be vertically polarized In like manner, a horizontally mounted dipole will produce a horizontal electric field and is horizontally polarized Equal vertical and horizontal E-field components produce circular polarization

polarization
Radio waves exhibit the property of polarization, which is the plane of their electrical fields Polarization is typically referred to as being horizontal or vertical, but the actual polarization can be at any angle Circular polarization is also possible Receiving a horizontally polarized signal with an antenna oriented to be vertically polarized, or vice versa, will slightly reduce the amount of signal received

It is chiefly due to the hydrogen, and results in an increase of the resistance, and the setting up of an opposing electro- motive force, both of which tend materially to weaken the current of the battery, or that passing through the cell

Restriction of the vibrations of the electromagnetic field to a single plane, rather than the innumerable planes rotating about the vector axis This prevents optical losses at interfaces between the lasing medium and optical elements Various forms of polarization include random, linear (plane), vertical, horizontal, elliptical, and circular Of two polarization components (so-called), S and P, the P component has zero losses at Brewster’s angle (See “BREWSTER WINDOWS ”) l = wavelength E = electric vector H = magnetic vector Wave amplitude of a plane-polarized beam
polarization
Property of certain types of electromagnetic radiation in which the direction and magnitude of the vibrating electric field are related in a specified way. The electric vector representing the magnitude and direction of the electric field in a wave of light is perpendicular to the direction in which the wave is moving. Unpolarized light consists of waves moving in the same direction with their electric vectors pointing in random orientations about the axis of propagation. Plane-polarized light consists only of waves that vibrate in one direction. In circular polarization the electric vector rotates about the propagation direction. Light may be polarized by reflection or by passing it through polarizing filters, such as certain crystals, that transmit vibrations in one plane but not in others. Polarized light has useful applications in crystallography, liquid-crystal displays, optical filters, and the identification of optically active chemical compounds
