摘要：

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 l*(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)=phi(F)/l*(Film)+phi(P)/l*(PB). Here phi(F) and phi(P)=1-phi(F) are the fraction of films and Plateau borders, respectively.
