Dielectric properties of soils at X-band microwave frequency

چکیده
Measurements of real (ε′) and imaginary (ε’’) parts of the complex dielectric constant (ε*) of soil with varied moisture content have been made at 9.44 GHz using infinite sample method. The electrical properties of dry soil samples are found to be in good agreement with the earlier work. The values of ε′ and ε′′ first increase slowly and then increase rapidly with moisture content. From this data, the ac conductivity and relaxation time are also reported in the present paper. The result shows the change in electrical properties of soils before and after the addition of water. These results provide a basis for using ground-penetrating radar or other high-frequency electromagnetic sensors in the detection of soil moisture content.

A dielectric mixing model has been developed to calculate the complex permittivity of wet soils at 5.65 GHz (C-band) and 9.5 GHz (X-band) microwave frequencies. The model considers the complex permittivity of dry soil as initial parameter. The complex permittivity of wet soil has been estimated in terms of the complex permittivity of dry soil, the complex permittivity of water at a given microw...
