Perfect depolarization in single scattering of light from uncorrelated surface and volume disorder

We demonstrate that single scattering of p-polarized waves from uncorrelated surface and volume disorder can lead to perfect depolarization. The degree of polarization is shown to vanish in specific scattering directions that can be characterized based on simple geometric arguments. Depolarization results from the different polarization response of each source of disorder, providing a clear physical interpretation of the depolarization mechanism.
