Samples from cohesive soil horizons, with different physical properties were extracted from boreholes made across the Timis Plain, West Romania region, with the aim of determining their electromagnetic properties. The frequency (ω) and volumetric water content (θ) dependencies of the complex dielectric permittivity, and complex magnetic permeability, of the soil samples, over the frequency range of 10kHz to 2MHz, have been investigated. Using the complex dielectric and magnetic measurements for various volumetric water content values, the frequency (ω) dependence of the attenuation parameter, α, the phase constant, β, the propagation constant, γ, and the reflection coefficient, R, was determined. The results are correlated with the dielectric relaxation and electric conductivity absorption processes over the investigated frequency range. The data obtained is very important for different applications of nondestructive testing on soils, and in evaluating the data obtained from ground-penetrating radar (GPR) investigations.
