Generalized refractive mixing dielectric model for moist soils

In this paper, a technique for estimating the maximum bound water content and complex dielectric constants for both the bound and the free water in soil is presented. The thus attained dielectric properties for the water in soil, are used to derive the Debye spectroscopic parameters for both types of water. Empirical data sets for the soil complex dielectric constant as a function of moisture measured only at two frequencies are sufficient for applying this technique. As a result the model for predicting soil complex dielectric constant in the microwave band is proposed and validated.
