Effective medium approximations - Wikipedia

In this paper we discuss the implementation of different equilibrium concentrations in each of the phases into the Maxwell-Garnett effective medium formula for diffusion in heterogeneous media. We put the derivation given by Kalnin et al., J. Phys. Chem. Solids, 2002, 63, 449, on safer grounds and extend it

Applicability of Effective Medium Approximations …

The Hashin–Shtrikman bound . is equivalent to the Maxwell Garnett estimate of the HCM relative permittivity, based on the homogenization of a random dispersal of spheres of component material 'a' embedded in the host component material 'b', valid for .[18 Maxwell Garnett JC.

This paper responds to the recent needs for homogenized models of bi-phased mixtures, compatible with the FDTD electromagnetic simulation method. We propose an explicit transformation of the Maxwell-Garnett mixing rule to the Debye relaxation formula. For that purpose, both models are rearranged into rational functions, and the conditions for their equivalence …

It is possible to continue to elaborate on these limits as they apply in Abe and Gomi's [4] work however, it must be emphasized that these restrictions actually apply to the effective medium type of approach to the problem as described by Maxwell Garnett [6], Bruggemann [7] and others [8,9].

From Maxwell Garnett to Debye Model for …

Effective medium approximations (abbreviated as 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 make up the composite material.
