Faraday effect and multiple scattering of light

摘要: The presence of a magnetic field in an optically active medium produces rotation the polarization light: it is well-known Faraday effect, which breaks time-reversal symmetry. averaged light intensity multiple scattering by disordered systems described weak-localization theory based on direct and reverse sequences scatterings, are founded electromagnetic (vectorial) waves spherical particles considered field. We have shown that electric reversed path can be obtained from one simple matrix transposition. In reduced dimensionality (1 2), we for same channel, peak backscattering cone not affected effect even though symmetry broken. correlation function one-dimensional system. This model furnishes two results: (i) wave vector randomized, there no decorrelation paths length (ii) has oscillatory behavior as three dimensions, calculated analytically attenuation well Rayleigh scattering. Mie been Monte Carlo simulations. diffusion regime (thick slabs) our results accord with previous experiments. Nevertheless, intermediate transmission, found oscillations For reflection strong field, observed convergence enhancement factor to nontrivial asymptotic values.
