We examine the coherent opposition effect from a medium containing arbitrary scatterers. A rigorous analysis of all interactions is numerically unwieldy, so we examine first and second-order effects. We proceed to a ray-tracing analysis. While not as elegant, the results are more easily accessible, and the effect of multiple interactions can be examined with relative ease. While scattering from small particles leads to a negative polarization opposition effect, scattering from larger spheres, comparable to the wavelength can lead to a positive or negative polarization opposition effect.
