WebJan 20, 2015 · Similar to the results for the isotropic media 17, the effective permittivity and permeability are determined by monopolar (m = 0) and dipolar (m = 1) modes, respectively. For the anisotropic case ... In materials science, effective medium approximations (EMA) or effective medium theory (EMT) pertain to analytical or theoretical modeling that describes the macroscopic properties of composite materials. EMAs or EMTs are developed from averaging the multiple values of the constituents that directly … See more There are many different effective medium approximations, each of them being more or less accurate in distinct conditions. Nevertheless, they all assume that the macroscopic system is homogeneous and, typical of all mean … See more In the Maxwell Garnett approximation, the effective medium consists of a matrix medium with $${\displaystyle \varepsilon _{m}}$$ and inclusions with $${\displaystyle \varepsilon _{i}}$$.
