Oct 01, 2004· Kerr spectra of Ni nanoparticles in SiO 2 were calculated using the improved LS theory, which is an extension of Maxwell-Garnett (MG) theory to magnetic composites with inclusion of the size-dependent Drude free-electron term and the size-independent bound-electron term. The experimental spectra qualitatively agree with the calculated ones ...

Maxwell Garnett Rule for Dielectric Mixtures with ...

An analytical model of a composite dielectric presented in this paper is the extension of Maxwell Garnett formulation. It takes into account the simultaneous statistical (Gaussian) distribution of conductivity and aspect ratio of inclusions. The inclusions are randomly oriented elongated conducting spheroids at concentrations below the percolation threshold.

The Maxwell‐Garnett theory is generally used to describe the optical behavior of aggregated metallic films. This theory is, however, restricted to ultrafine particles whose main dimension can be considered very small compared to that of the wavelength. With particle dimensions in experiments generally larger than 10 nm, this approach is no longer valid for many metals.
