Ratio of the Rayleigh scattering cross section of a randomly oriented oblate or prolate spheroid, $〈 C_{sca}^{spheroid} 〉$ $\langle C_{{\rm{sca}}}^{{\rm{spheroid}}}\rangle$ , to that of a sphere of the same volume, $C_{sca}^{sphere}$ $C_{{\rm{sca}}}^{{\rm{sphere}}}$ . The dielectric permittivity of pores and host medium are ε_pore = 1 and ε_bulk = 2, respectively.
