“Computation of the effective dielectric constant of a two- component, three-dimensional composite materials using simple poles”, Journal of Applied Physics, Vol. 82, No. 1, 1997.
Bergman and Milton proved that the effective dielectric constant or conductivity of a two-component composite material is a function of the ratio of the dielectric constants or conductivities of the components which can be described by a series of simple poles and residues. These poles and residues are determined only by the microgeometry of the composite. In this study, we use a simplified three-dimensional Fourier series expansion method to locate the poles and residues for simple cubic, body-centered, and face-centered lattices in different concentrations. Comparison between the simple pole theory and the Fourier series expansion method shows a good agreement. © 1997 American Institute of Physics.
