Complex Permittivity of Mixtures of Sand With Aqueous NaCl Solutions Measured at 2.5 GHz
Abstract
The complex permittivity of a quartz sand mixed with aqueous solutions of NaCl has been measured at frequency of 2.5 GHz employing dielectric ring resonator operating on TE 01δ mode. Measurements have been taken for various concentrations of NaCl up to saturation at the temperature about 22 C. It has been shown that both the real part and the imaginary part of permittivity of the moist sand are strongly related to the dielectric properties of aqueous solution of NaCl. The real part of the complex permittivity of moist sand decreases, while the imaginary part of the complex permittivity increases with the NaCl concentration
