In this paper we use fundamental and measurable parameters to build components of a combined dielectric model for composite materials. Beginning with a near ideal material such as sand with pseudo-spherical particles, and using measureable parameters such as particle size distribution, we derive a model and demonstrate the relationship between the complex permittivity calculated by the model over 2 to 6 GHz, for a volumetric moisture content range from 0 to 0.30. The model predictions were validated by physical measurements in low-loss material with discrepancies of less than 1% V/V moisture content.
