Code 8.12: Mie and Rayleigh Scattering

Code Name: Mie_Rayleigh_ScatteringOfSpheres.m

Description: Code computes the absorption, scattering, extinction, and backscatter efficiencies of a dielectric sphere according to both the Mie solution and the Rayleigh approximation.

Input Variables:

  εp = εp ' - jεp '':    Dielectric constant of the spherical particle (unitless)
  εb = εb ' - jεb '':    Dielectric constant of the background medium (unitless)
  f:    Frequency (GHz)
  r:    Sphere radius (m)

Output Products:

  ξa m:    Mie absorption efficiency (unitless)
  ξs m:    Mie scattering efficiency (unitless)
  ξe m:    Mie extinction efficiency (unitless)
  ξa R:    Rayleigh absorption efficiency (unitless)
  ξs R:    Rayleigh scattering efficiency (unitless)
  ξe R:    Rayleigh extinction efficiency (unitless)
  ξb m:    Mie backscattering efficiency (unitless)
  ξb R:    Rayleigh backscattering efficiency (unitless)
