Particle Shape Effects
Particle shape can impact dielectric measurements in a significant way based on the aspect ratio of particles and orientation with respect to the applied EM field.

Surface Area
Soil surface area has been considered a contributor to reduced permittivity-soil water content relations due to binding of water molecules. Others suggest it is the water-solid-air phase configuration that contributes to lowering of dielectric-water content curves.

Three-Phase Mixtures
Three-phase mixtures are useful for describing the water-air-solid phases of soil and other porous media.
