English: Note that this is a LEFT-handed/clockwise circularly polarized wave as defined from the point of view of the RECEIVER.

It is RIGHT-handed/clockwise circularly polarized wave as defined from the point of view of the SOURCE.
Refer to Circular polarization Handedness conventions for clarification.

The horizontal component and its corresponding plane are illustrated in green while the vertical component and its corresponding plane are illustrated in blue. Given that this is left-handed circularly polarized light, the leftward (relative to the direction of travel) horizontal component leads the vertical component by one quarter of a wavelength. This phase quadrature results in the points of maximum magnitude for the vertical component corresponding to the points of zero magnitude for the horizontal component, and visa versa. The result is that there are select vectors, corresponding to the helix, which exactly match the maximums of the vertical and horizontal components. To minimize visual clutter these are the only helix vectors displayed.
