The effective medium calculator (EMC) is an interactive program for manipulating optical constants of different materials with special attention to their combination by effective medium theories. Up to six media may be mixed using the Bruggeman or Maxwell-Garnett approach for arbitrary shapes of the components. The computed constants can be stored or used in further calculations. All computations can be controlled by eye via graphical plots.
