The effective permittivity of the discrete random medium composed of dielectric spheres and homogeneous space in the region of low to resonance frequencies

Presents the effective permittivity of the discrete random medium where dielectric spheres are randomly distributed for a coherent field, in the region of low to resonance frequencies. In addition, the authors have in part compared the results with those of the effective field approximation, the quasi-crystalline approximation and the quasi-crystalline approximation and coherent potential.
