Abstract

The theoretical calculations of the far-IR absorption by composites with small metallic inclusions are performed. The main electrostatic assumption of electrically small inclusions in the case of high conductive particles in the far-IR range is not valid. The modified expressions for the dielectric and magnetic permeability of the metallic inclusions are obtained using Mie theory. The calculated absorption spectra of Pd-KCl composite in the far-IR region are in good agreement with experiment.
