Anomalous far-infrared absorption in random small-particle composites
TLDR
In this article, the frequency dependence and magnitude of the far-infrared absorption of a small-metal-particle composite material have been measured over the range of 4-100 cm.Abstract:
The frequency dependence and magnitude of the far-infrared absorption of a small-metal-particle composite material has been measured over the range of 4-100 ${\mathrm{cm}}^{\ensuremath{-}1}$. The composite samples consisted of spherical metal particles, with radii varying from 100-1000 \AA{}, randomly dispersed in an insulating host. In some samples, a nonlinear dependence of the absorption on the metal-particle concentration was observed, indicating that interparticle interactions can play an important role. It is shown that the magnitude of the absorption cannot be explained by classical electromagnetic theory.read more

Dielectric constant of a composite inhomogeneous medium
Petr Chýlek,Vandana Srivastava +1 more
TL;DR: In this paper, the authors derived an expression for the effective dielectric constant of a composite medium considering the contributions from both the electric and the magnetic dipole terms, and showed that the form of the size distribution of small metallic particles determines the value of the volume fraction at which a sharp increase in ac absorption of composite material occurs.
