Code 12.8: Incoherent Emissivity of a Two-Layer Composite

Code Name: Incoh_Emissivity_TwoLayer.m

Description: Code computes incoherent emissivity of an inhomogeneous layer separated by air on top and a homogeneous medium on the bottom, with perfectly smooth parallel boundaries on both sides.

Input Variables:

  ε2 = ε2 '- jε2 '':    Dielectric constant of middle layer (unitless)
  ε3 = ε3 '- jε3 '':    Dielectric constant of bottom layer (unitless)
  Θ1:    Incidence angle in air (degrees)
  a:    Single-scattering albedo (unitless)
  κe:    Extinction coefficient (Np/m)
  d:    Layer thickness (m)

Output Products:

  einc v (Θ1):    v-polarized emissivity (unitless)
  einc h (Θ1):    h-polarized emissivity (unitless)

Book Reference: Section 12-12.2
