Microstructural Effects on Dielectric Constants of Two-Phase System

Abstract

The dielectric properties of the binary phase mixture have been investigated theoretically in the effective medium approximation with applications to porous glasses and Mg-PSZ. It is shown that the static dielectric constant of porous glass depends very little upon the pore geometry and size, but can be used for estimating the porosity of the material. In the far-infrared absorption of Mg-PSZ, we show that the calculated effects of the microstructure of the constituent phase are significant on the excitation spectra of the surface polaritons.
