SCATTERING CORRECTIONS FOR MAXWELL GARNETT MIXING
1999年8月20日 Correction terms are derived for the polarizability of a dielectric sphere and Maxwell Garnett mixing formula. The correction terms take into account the size of the scatterers, and therefore depend on the frequency of the incident field. However, the limitation of the mixing rule result is that the volume fraction of the inclusions has to be small.

Maxwell–Garnett model for thermoelectric materials
2020年10月1日 To find it, one can use the well-known formulas of Maxwell–Garnett and Bruggeman (Garnett, 1905). We assume that the electric and thermal fields are determined by the external potential φ ext and the external temperature field T ext , i.e., away from the inclusion (6) ϑ → T ext , φ → φ ext , Φ → φ ext + α m T ext .

2005年7月25日 We give a rigorous and original derivation of the Maxwell-Garnett mixing rule in the dynamical regime for a composite dielectric random medium with small spherical inclusions. For certain configurations of scatterers, we show that contrarily to the common belief, the Maxwell-Garnett formula can remain very accurate at a high concentration of scatterers and

Maxwell Garnett approximation in random media: tutorial.
2022年2月14日 In the third part of the tutorial, we develop a Maxwell Garnett approximation, which is applicable, in particular, to disordered random media with non-spherical inclusions and to multicomponent mixtures. We are especially interested in the case when the inclusions are non-spherical and randomly distributed and oriented in space, but the composite is isotropic on

2000年8月15日 The optical properties of heterogeneous materials can be described in terms of effective dielectric constants. Two widely used effective medium theories are the Maxwell-Garnett (MG) theory [1] and the Bruggeman theory [2].In both theories the effective dielectric constant does not depend explicitly on the size of the grains or inclusions occurring inside the

Full dynamic corrections to the Maxwell Garnett mixing formula
Here we derive a full dynamic extension to the Maxwell Garnett mixing formula for the effective refractive index of a random system of particles that takes proper account of scattering by the particles even for moderate densities. The new formula exhibits the so-called dependent-scattering effects, which are strongest, in relative terms, in colloidal systems with small non
