Popis: Precise knowledge of the frequency dependent electromagnetic properties of porous media is urgently necessary for successful utilization of high frequency electromagnetic measurement techniques for near and subsurface sensing. Thus, there is a need of systematic investigations by means of dielectric spectroscopy of unsaturated and saturated soils under controlled hydraulic conditions. In this context, two-port rod based transmission lines (R-TMLs) were characterized in the frequency range from 1 MHz to 10 GHz by combined theoretical, numerical, and experimental investigations. To analyze coupled hydraulic and dielectric soil properties a slightly plastic clay soil was investigated. There is evidence that the bound water contribution of the soil is substantially lower than expected.
