Abstract :
The concepts of effective permittivity and permeability are used throughout the literature to describe heterogeneous materials, inhomogeneous materials, and small collections of molecules. In this paper we study definitions of the permittivity and permeability based on the microscopic Maxwell\´s equations and then discuss the ramifications of the common usage of the term "effective".
