Impacts of the Real and Imaginary Components of Relative Permittivity on Time Domain Reflectometry Measurements in Soils

Time domain reflectometry (TDR) is widely used for routine field monitoring of water content and salts in soils. Most estimates of water content assume the TDR‐measured apparent relative permittivity, ϵa, is a good approximation for the real component, ϵ′r, of the soil's complex relative permit...
