Dielectric response of matter with cubic, circular-cylindrical, and spherical microstructure

The effect of the microstructure of heterogeneous matter on its macroscopic dielectric properties is studied. The basic polarizable elements are allowed to be either homogeneous spheres (which is the classical Lorenz–Lorentz case), cubes, or circular cylinders. Accurate numerical estimates are given...

Summary:The effect of the microstructure of heterogeneous matter on its macroscopic dielectric properties is studied. The basic polarizable elements are allowed to be either homogeneous spheres (which is the classical Lorenz–Lorentz case), cubes, or circular cylinders. Accurate numerical estimates are given for the polarizability of these shapes as functions of the permittivity, and these are applied to estimate the effective permittivity of mixtures where such scatterers are embedded in a background medium. Physical interpretations are given for the behaviour of the dielectric response of these various inclusions. © 2004 Wiley Periodicals, Inc.
