The ratio of the semimajor to semiminor axis is |(1 + r)/(1 − r)|, where<br />
E−/E+ = r.<br />
If the amplitudes have a phase difference between them E−/E+ = re iα ,<br />
then the ellipse traced out by the E vector has its axes rotated by an<br />
angle α/2.<br />
Figure: The figure shows the general case of elliptical polarization and<br />
the ellipses traced out by both E and B at a given point in space.<br />
Note : For r = ±1 we get back to a linearly polarized wave.<br />
