There exists several competing conventions on how to measure polarization in use throughout different optics communities [1]. As outlined in the parent section ScatteringMatrix, by default the convention described in PlaneWave is used.

Other popular convention differ from this definition in three key aspects:

- the time-harmonic phase dependency
- the choice of sign of the fourth Stokes-parameter
- whether or not the coordinate system is switched on reflection

The convention used by `JCMsuite`

depends on the propagation direction, hence the S-polarization changes its sign in a reflection measurement. Furthermore, as noted in here the angular frequency dependence in the fields is given by , whereas conventions used in the ellipsometry community usually assume . The fourth Stokes-parameter distinguishes left and right handed polarization and offers an additional choice of sign.

The additional conventions are
