    Author(s): Jitendra Behari and V. SharmendraJitendra Behari and V. Sharmendra

    Surface soil moisture is important to understand environmental systems and dielectric constant is a convenient physical parameter to describe this. Dielectric Mixing models relate the effective dielectric constant of a heterogeneous medium with the properties of constituent materials. The dielectric properties of the soil is known to have dependence on Soil moisture content along with other factors like texture, frequency, salinity etc. In this investigation, experimental data of Dielectric Constant of various types of soil has been taken at 1.4 GHz and 18 GHz to fit unknown parameters in modified Rayleigh mixing model. Calculation of Effective dielectric constant and emissivity of different types of soil has been carried out and using modified Debye formulation, spread in relaxation and relaxation frequency is also obtained. Effective dielectric constant increases with rise in volume.. Read More»
