| Abstract: | We develop a second-order model of the light scattered by a cloud of randomly positioned dipoles and consider the interference of reciprocal rays that lead to enhanced backscatter and negative polarization. For large pathlength separations, we derive analytic expressions for the individual polarization intensities. |
