Polarization Definition from Language, Idioms & Slang Dictionaries & Glossaries
Webster's Revised Unabridged Dictionary (1913)
(n.)
The act of polarizing; the state of being polarized, or of having polarity.
  
(n.)
An effect produced upon the plates of a voltaic battery, or the electrodes in an electrolytic cell, by the deposition upon them of the gases liberated by the action of the current. 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.
  
(n.)
A peculiar affection or condition of the rays of light or heat, in consequence of which they exhibit different properties in different directions.

Polarization Definition from Science & Technology Dictionaries & Glossaries
Electrochemistry Dictionary
"The change of potential of an electrode from its equilibrium potential upon the application of a current. See overpotential for a more detailed description. Somewhat confusingly, the term ""polarization"" is often also used in place of overvoltage. "
Telecommunication Standard Terms
Of an electromagnetic wave, the property that describes the orientation, i.e., time-varying direction and amplitude, of the electric field vector. (188 ) Note 1: States of polarization are described in terms of the figures traced as a function of time by the projection of the extremity of a representation of the electric vector onto a fixed plane in space, which plane is perpendicular to the direction of propagation. In general, the figure, i.e., polarization, is elliptical and is traced in a clockwise or counterclockwise sense, as viewed in the direction of propagation. If the major and minor axes of the ellipse are equal, the polarization is said to be circular . If the minor axis of the ellipse is zero, the polarization is said to be linear . Rotation of the electric vector in a clockwise sense is designated right-hand polarization , and rotation in a counterclockwise sense is designated left-hand polarization . Note 2: Mathematically, an elliptically polarized wave may be described as the vector sum of two waves of equal wavelength but unequal amplitude, and in quadrature (having their respective electric vectors at right angles and /2 radians out of phase).
Satellite TV Glossary
Signals downlinked from communications satellites often circularly polarized. The electric and magnetic fields rotate in a circular motion as they travel through space, analogous to movement along a spiral. The direction of rotation determines the type of circular polarization. A signal whose electric or magnetic fields rotate in a right-hand direction is termed right-hand circular polarized (RHCP); a signal rotating in the left-hand direction is termed left-hand circular polarized (LHCP). The use of circular polarization eliminates the need for skew adjustment in the reception equipment. In addition, circularly polarized signals are also not subject to Faraday Rotation, the rotation of polarity caused by the Earth's magnetic field and/or magnetic storms when a signal travels through the atmosphere. This resistance to Faraday rotation makes circular polarization eminently more suitable than linear polarization for voice and data relays via satellite. Adjacent high-powered direct broadcast Ku-band satellites in Europe have been configured to use opposite senses of circular polarization to decrease interference between satellites by virtue of cross-polarization discrimination built into the feed.
AJA_RF Technical and TestTerminology
Orientation of the electric field vector of a radiated field.
RF Electronics
The ability of electromagnetic waves to vibrate in different radial directions. Typically, horizontal or vertical directions. A characteristic of the electric field on an electromagnetic wave in space. Four types of polarization are used with communications satellites: horizontal, vertical, right-hand circular, and left-hand circular.
WEATHER&METEOROLOGY
The plane of vibration for a wave, usually electromagnetic. Can be a factor in determining scattering and absorption properties.
Technical English by wpv
The inability of an electrode to reproduce a reading after a small electrical current has been passed through the membrane. Glass pH electrodes are especially prone to polarization errors caused by small currents flowing from the pH meter input circuit and from static electrical charges built up as the electrodes are removed from the sample solution, or when the electrodes are wiped.
Astronomy and Physics Terms by ExploreSpace.com
A special property of light; light has three properties, brightness, color and polarization.
Fiber Optics, Optical Networking Terms
The direction of the electric field in an electromagnetic wave.
