The frequency dependence of soil electromagnetic properties contain valuable information of the porous material due to strong contributions to the dielectric relaxation behavior by interactions between aqueous pore solution and mineral phases due to interface effects. Soil hydraulic properties such as matric potential are also influenced by different surface bonding forces due to interface processes...
The most important parameter affecting ground-penetrating radar (GPR) measurements is the complex effective relative permittivity ɛ r,eff* because it controls the propagation velocity and the reflection of GPR pulses. Knowing ɛ r,eff* of soils passed through by electromagnetic waves increases accuracy in soil thickness and interface identification. Complex effective relative permittivity ɛ r,eff...
