Maxwell-Garnett EMA

This possibility is extremely useful for the structural characterization of polymer blends. The optical properties of the polymer layer can be described by a so-caUed effective dielectric function, which is a suitable average of the dielectric functions of the two components. Three averaging effective medium approximation (EMA)s -the linear, Maxwell-Garnett and Bruggeman EMAs - are widely used for this purpose [9]. These approximations differ in their spectral densities for a given volume fraction. 

The linear EMA is a simple linear interpolation between the constituent optical constants this EMA is not highly accurate, but is often used for graded layers to reduce the calculation time a +/b 

The Maxwell-Gamett EMA [10] is developed for very diluted collections of small particles (in dipole approximation)
