| Description: | Technical Report Abstract: Making use of a coaxial reflection/transmission experimental procedure described in Report 2 of this series, a large number of complex dielectric property measurements were made of soil samples that ranged in texture from a poorly graded sand to a pure nonswelling clay mineral. Two methods of modeling the results are discussed. One is an equivalent circuit representation that accounts for both low-frequency conductivity and higher frequency dielectric relaxation losses in the soil/water mixture. The other model consists of a fractal description of soil structure combined with the concept of long-range electrical connectivity at less than 100 percent saturation. |
