An existing 2D concept for the numerical estimation of effective dielectric properties of mixtures with random droplets' distribution was adapted here and expanded into 3D. The expansion of the concept to 3D introduces a new possibility for direct comparison of simulation results with measured values. Simulated effective permittivity of Water-in-Oil as well as of Oil-in-Water emulsions were compared to data estimated using two mixing formulas: Maxwell Garnett and Bruggeman. Dielectric properties estimated with the Maxwell Garnett mixing formula fits better dielectric properties of both Oil-in-Water and Water-in-Oil emulsions. Furthermore, dielectric properties of Oil-in-Water emulsions were measured using a commercial system Dielectric Probe Kit from Agilent Technologies. The measured data were compared with the dielectric properties estimated using both the Maxwell Garnett mixing formula and the numerical concept. All compared data fit well each other.
