Fractal diffusion front in a bidimensional medium obtained by means of identical interacting particles with spatial Fourier filtering [Front fractal de diffusion dans un milieu bidimensionnel obtenu grâce à des particules identiques en interaction et à un filtrage de Fourier].




Initially, a set of strictly identical particles is disposed on a bidimensional square lattice. All particles have the same velocity modules when the velocity directions are randomly chosen. The Red an Blue colors are used only to tag the particles. A spatial Fourier filtering is done on each picture.
