Definition: | an elliptically or circularly-polarized wave in which the electric field strength vector, observed in any fixed plane normal to the direction of propagation, whilst looking in this direction, rotates with time in a left-hand or counterclockwise sense
NOTE – For a left-hand circularly-polarized plane wave; the ends of the electric vectors drawn from any points along a straight line normal to the plane of the wave front, form, at any instant, a right-hand helix.
