Code 4.7: Relative Dielectric Constant of Soils

Code Name: RelDielConst_Soil.m

Description: Code computes dielectric constant of soil.

Input Variables:

  T:    Temperature (°C)
  f:    Frequency (GHz)
  ρb:    Soil bulk density (g/cm3)
  mv:    Volumetric moisture content (0 ≤ mv ≤ 1)
  S:    Sand fraction (0 ≤ S ≤ 1)
  C:    Clay fraction (0 ≤ C ≤ 1)

Output Products:

  ε' soil:    Real part of dielectric constant of soil (unitless)
  ε'' soil:    Imaginary part of dielectric constant of soil (unitless)

Book Reference: Section 4-8 and Eq. (4.66) for f > 1.3 GHz, or Eq. (4.66) and Eq. (4.70) replacing Eq. (4.68d) for 0.3 ≤ f ≤ 1.3 GHz.
