    "abstract": "We consider the effect of spatial correlations on sources of polarized\nelectromagnetic radiation. The sources, assumed to be monochromatic, are\nconstructed out of dipoles aligned along a line such that their orientation is\ncorrelated with their position. In one representative example, the dipole\norientations are prescribed by a generalized form of the standard von Mises\ndistribution for angular variables such that the azimuthal angle of dipoles is\ncorrelated with their position. In another example the tip of the dipole vector\ntraces a helix around the symmetry axis of the source, thereby modelling the\nDNA molecule. We study the polarization properties of the radiation emitted\nfrom such sources in the radiation zone. For certain ranges of the parameters\nwe find a rather striking angular dependence of polarization. This may find\nuseful applications in certain biological systems as well as in astrophysical\nsources.",
