Page "Circular polarization" Paragraph 4

On the right is an illustration of the electric field vectors of a circularly polarized electromagnetic wave.

The electric field vectors have a constant magnitude but their direction changes in a rotary manner.

Given that this is a plane wave, each vector represents the magnitude and direction of the electric field for an entire plane that is perpendicular to the axis.

Specifically, given that this is a circularly polarized plane wave, these vectors indicate that the electric field, from plane to plane, has a constant strength while its direction steadily rotates.

It is considered to be right-hand, clockwise circularly polarized if viewed by the receiver.

Since this is an electromagnetic wave each electric field vector has a corresponding, but not illustrated, magnetic field vector that is at a right angle to the electric field vector and proportional in magnitude to it.

As a result, the magnetic field vectors would trace out a second helix if displayed.
