A physically-based model often used in satellite missions like SMAP and SMOS.

or permittivity) , which describes how the soil interacts with electromagnetic radiation . This property is highly sensitive to moisture because dry soil has a low dielectric constant (~3–5), while liquid water has a significantly higher one (~80). 1.

Dielectric behavior varies across the microwave spectrum (typically 1.4 GHz to 18 GHz). Dispersion is most pronounced in the imaginary part (loss factor) due to ionic conductivity and molecular relaxation. Microwave Dielectric Behaviour of Wet Soils
