Abstract:A novel method based on the statistical model of random medium and the FDTD method in two dimensions is developed to explain the electromagnetic wave spatial distribution in random medium. The relationship between the electromagnetic wave spatial distribution and the dielectric constant fluctuating was discussed based on photon localization theory. The numerical result shows that the fluctuating of the spatial distribution of the scatterers can form some special configuration. This configuration has directly effect on characteristic of localization of electromagnetic wave.
Keywords:Random medium  Photon localization  FDTD method  Fluctuating
