Abstract
We study the propagation of a stochastic electromagnetic beam through a chiral medium. The cross-spectral density matrix is deduced and employed to calculate the changes in the spectral degree of polarization of the beam on propagation. It is shown that the spectral degree of polarization can be modulated by changing the chiral parameter of the medium and the coherent parameter of the beam. Also, it is interesting to find that the spectral degree of polarization of a stochastic electromagnetic beam on propagation in far zone is different from that of the source.
