The Application of the Theory of Heterogeneous Dielectrics to Low Surface Area Soil Systems

A theory of a three component heterogeneous dielectric has been developed to provide a basis for an analytic description of the electromagnetic properties of soil systems. The theory is valid for frequencies where the electromagnetic wavelength is much greater than the particle size. Essential parameters of the theory ase the amounts and properties of the separate constituents. Agreement between theory and experiment for low surface area sand systems at both audio and p-band radar frequencies is demonstrated.
