Figure (4.11) shows that the polarizing device could be described by a 2 × 2 transfer matrix, i.e. the Jones matrix [J]. It relates the output of the device to its input. The input could be the incident wave at certain slab/surface, acting as a polarizing device, and the output could be the transmission or reflection of the waves.

Figure 4.11 Polarizing device described by Jones matrix.

The Jones matrix elements are interpreted in the terms of the co‐polarized and cross‐polarized outgoing waves after transmission/reflection from a slab/surface:

(4.6.14)

where J_yy and J_zz are responsible for the co‐polarized outgoing waves, and J_yz and J_zy account for the presence of cross‐polarized waves at the output. The co‐polarized output waves have the same polarization as that of the incident input waves. Whereas, the cross‐polarized output waves have orthogonal polarization with respect to the polarization of the incident input waves.
