Abstract

The effective-medium model has been generalized within the dipole approximation, with allowance for the shape anisotropy and dynamic depolarization of semiconductor nanoparticles. The calculations revealed nonmonotonic dependences for the birefringence and dichroism on the nanoparticle size. Comparison of the measured and calculated refractive index dispersion of birefringent porous silicon layers in the near-IR region indicates that consideration for the dynamic depolarization gives a better description of the optical properties for this material in comparison with the generally used effective-medium electrostatic approximation.
