Dielectric model of moist soils with varying clay content in the 0.04 to 26.5 GHz frequency range

In this paper, a soil texture dependent multi-relaxation generalized refractive mixing dielectric model (MR GRMDM) for moist soils was developed. The model provides for complex permittivity of moist soils in both the gigahertz and megahertz frequency ranges, namely, from 40 MHz to 26.5 GHz.
