Lg. Grechko et al., Macroscopic dielectric response of the metallic particles embedded in hostdielectric medium, MICROEL REL, 40(4-5), 2000, pp. 893-895
A theoretical approach is proposed to calculate an effective dielectric con
stant of a matrix disperse system (MDS) of metallic particles (spheres) ran
domly distributed and embedded in a uniform dielectric medium. Deviations f
rom the well-known Maxwell-Garnett formula have been observed. The effectiv
e dielectric constant for different volume fractions of the embedded partic
les is considered as well as the dependence on pair interaction between par
ticles, and the relation between sizes of each pair of particles. The probl
em is solved in the electrostatic approximation. (C) 2000 Elsevier Science
