Propagation Properties of Completely Unpolarized Beams and Completely Polarized Beams
It is found that both the completely unpolarized stochastic electromagnetic beams and completely polarized stochastic electromagnetic beams will keep their spectral degree of polarization or become partially polarized under different constraint conditions during their propagation in free space. It is shown that it depends on δ denoting the variance of the correlations between the components of the field and σ denoting the variance of the intensity distribution across the source.
