left-hand polarization

left-hand polarization

[′left ¦hand ‚pō·lə·rə′zā·shən]
(electromagnetism)
In elementary-particle discussions, circular or elliptical polarization of an electromagnetic wave in which the electric field vector at a fixed point in space rotates in the left-hand sense about the direction of propagation; in optics, the opposite convention is used; in facing the source of the beam, the electric vector is observed to rotate counterclockwise.

Clockwise rotation of the electric field vector is designated as right-hand polarization (RH) and counterclockwise rotation is left-hand polarization (LH), for an observer looking in the direction of propagation.
