Debye Coefficients for Low Frequency FDTD Dispersive Soils Analysis

Determining Debye coefficients for soils will facilitate an accurate modeling with dispersive FDTD formulation for borehole induction logging. In this paper, a two-term expansion of Debye coefficients for a given sample of soil data are determined via a two-step numerical solver. The Debye coefficients obtained matched up precisely with the permittivities of the given data.
