Calculation of the Mueller matrix for scattering of light from two-dimensional rough surfaces

PA Letnes, AA Maradudin, T Nordam, I Simonsen - Physical Review A, 2012 - APS
We calculate all the elements of the Mueller matrix for light scattering from a two-dimensional
randomly rough lossy metal surface. The calculations are carried out for arbitrary angles of …
