The phase difierence depends on the incident wavelength, the refractive indices (along the two difierent direc-tions) and the thickness of the crystal. The slope of a linear-polarization curve is controlled mainly by icorr and is insensitive to changes in α and β values as shown in Equation (19). This Jones matrix is not the same as the polarization rotation matrix since the rotation is dependent on the polarizer angle. ' • Interference only occurs when EM waves have the same frequency and polarization (i. Note that linear polarization and circular polarization can be seen as special cases of elliptical polarization. If the orientation of E (q in Fig 1) remains fixed as the wave moves forward, the light is plane-polarized.
