Correlating dielectric properties of solids and particulate samples through mixture relationships
1992
Nelson, S.O.
Six dielectric mixture equations are presented and evaluated for usefulness in calculating the dielectric properties (relative complex permittivities) of solid materials from measured permittivities of air-particle mixtures consisting of granular and pulverized forms of the solid material. Examples presented are for whole-kernel and ground hard red winter wheat, Triticum aestivum, L. and ground white rice, Oryza sativa, L. The Complex Refractive Index and Landau and Lifshitz, Looyenga mixture equations, and extrapolations of functions of the dielectric properties which are linear with mixture density and consistent with these mixture equations, provide the best estimates of the solid material permittivities. Relationships are also presented for converting dielectric properties of an air-particle mixture at a known density to those of the mixture at any other density.
