A whole chapter has now been devoted to the introduction of the basic Maxwell Garnett mixing formula and various analytical exercises to illustrate the theory. The mixing analysis was in many respects idealised. The mixture consisted of two phases and the inclusions were assumed to be spherical in shape. It is perhaps time to relax these assumptions and try to see whether it is possible to say more about mixtures. In the present section, let us generalise the Maxwell Garnett theory to allow variation in the structure and materials of the mixture.
