Monte Carlo simulation of electromagnetic wave propagation in dense randommedia with dielectric spheroids

We study the electromagnetic wave propagation in three-dimensional (3-D) de nse random discrete media containing dielectric spheroidal scatterers. We e mploy a Monte Carlo method in conjunction with the Method of Moments to sol ve the volume integral equation for the electric field. We calculate the ef fective permittivity of the random medium through a coherent-field approach and compare our results with a classical mixing formula. A parametric stud y on the dependence of the effective permittivity on particle elongation an d fractional volume is included.
