A Gaussian Model for Dielectric Permittivity in Moisty Soils

Complex permittivity of soil is connection with volumetric water content robustly. Especially, Dielectric constant rapidly varies with volumetric water content because of the robust connection between volumetric water content and dielectric constant, if volumetric water content is known, dielectric constant can quickly predict. If dielectric constant is known, volumetric water content can simply predict via mathematical models. Relation of dielectric constant and volumetric water content is investigated different environments with various soil textures. A Gaussian mathematical model is proposed by means of experimental data at 9.5 GHz. Proposed mathematical model is compared with different mathematical models
