Term: Linear polarization

Definition:

A fully-polarized EM wave in which the polarization ellipse reduces to a straight line.

Explanation:

For a linearly polarized EM wave, the tip of the electric field vector traces a straight line on a plane that is perpendicular to the wave propagation direction. Only the orientation angle y is needed to describe the polarization of the wave. Horizontal ( = 0 and 180°) and vertical ( = 90°) are the most common examples of linearly polarized waves.
