MieTab Mie Scattering Program MieTab is a Microsoft Windows application designed for making Mie Scattering calculations for a single homogenous sphere placed in a non-absorbing uniform medium. The optical properties of the medium and the sphere are entered by a user in the form of complex indices of refraction " m+ik ". For the medium hosting the sphere only thr real part (m) is used.

MieTab can also calculate first order scattering properties for polydisperse aerosols that can be charactersized by one of several particle size distribution models. In this document the term "first order scattering" means that no account is taken of multiple scattering or coherent scattering that might arise from interactions of non-random distribution of particle locations.

For the actual Mie computations, MieTab uses a computational model originally developed by J. V. Dave at IBM, but with the spherical functions calculated according to a scheme created by W. J. Lentz. Lentz's adaptation of the Dave code was extended by A. Miller to include calculations of intensities within a single sphere as well as the scattered intensities.

MieTab includes the following internal models:

  • A Single Mie Size-parameter
  • A range of Mie Size-parameters
  • A Single Radius at a Single Wavelength
  • A Range of Equally Spaced Radii at a Single Wavelength
  • A Range of Wavelengths with a Single Radius
  • Zero-Order Log-Normal Distribution
  • Power Law Distribution
  • Modified Gamma Distribution
  • Modified Gamma Distribution Fog Model
  • Marshall-Palmer Rain Model
  • Hybrid Log-Normal/Power Law Model
  • Double Exponential Distribution
  • User Supplied Distribution Model
  • Special (Details are in the mthelp.html file to which a link appears below.)

    With the second, third, fourth and fifth models listed above, either "efficiency factors" or "cross sections" can be specified as outputs. With the polydisperse particle models, only cross sections are calculated. Other possible outputs include Van de Hulst's "Modified Stokes Parameters" for a user entered incoming wave description (U,V)

    The standard outputs of MieTab calculations are displayed as tables, but users have the additional option of displaying on-screen graphs of most kinds of results.

    Several versions of MieTab exist - although there is no guarantee of future fixups for any of them because of Miller's age and health conditions.
