for the magnetic field, where k is the wavenumber,
is the amplitude of the field and
is the Jones vector in the x-y plane. Here is an angle that determines the tilt of the ellipse and determines the aspect ratio of the ellipse. If and are equal the wave is linearly polarized. If they differ by they are circularly polarized.
