The polarization of a light beam can be represented by its electric field vector. Its optical power is a scalar quantity that is proportional to the mean square of the electric field amplitude. Let z be the direction of propagation. Then, the polarization vector is in the x-y plane.Yes, a Jones vector can only represent the perfectly polarized part of the Stokes vector. And yes, because there is an arbitrary phase, there are an infinity of Jones' vectors that fit a given Stokes vector representation. However, that doesn't prevent us from constructing a Jones vector from a Stokes vector.

Now consider a uniformly polarized slab in which the polarization density vector lies in the plane of the slab as shown in Figure (2.7.12). In this case the polarization has only an x-component, and that x-component, P x, is a function only of z.The polarization vector points where E points. If it’s linearly polarized it stays in a plane. The combination of two linearly polarized waves with a phase shift between them gets you a circularly polarized wave.

Note that since k2 = m2 for a particle of mass m, it follows that εµ(~k, S)·εµ(~k , S)∗ = 1. In addition, εµ(~k, S)·εµ(~k, λ)∗ = 0

Resolving the original electric field vector into components parallel and perpendicular to the polarizing axis, and keeping only the parallel part means that the new electric field vector magnitude is: E′o = Eo cos ϕ (3.7.1) (3.7.1) E o ′ = E o cos ϕ. The electric field vector is the ... To achieve maximum output power from a receiving antenna, the matched antenna polarization vector must be the complex conjugate of the incoming field’s polarization vector. As an example, if the incoming field is RHCP, with polarization vector given by e r = 1 2 ( e x − i e y ) , the optimum receiver antenna polarization is LHCP.
