  4. Abstract:
  5. We study photon diffusion in a one-dimensional model foam composed of thin films and Plateau borders. Each thin film or Plateau border is characterized by its own intensity transmittance. We relate | Foam, the transport-mean-free path of photons diffusing in the foam, to the foam microstructure. Denoting by l Film (l PB) the transport-mean-free path of photons in a medium composed only of thin films (Plateau borders), we find 1/ l Foam = φF / l Film + φP / l PB. Here φF and φP =1- φF are the fraction of films and Plateau borders, respectively
