Light scattering calculator: homogeneous sphere (HSS)

Function

The HSS light scattering program calculates the angular scattering pattern, as well as the scattering, absorption, and attenuation parameters of a single homogeneous sphere and a size-distributed dispersion of spheres according to Mie theory (Mie, 1809) with algorithms introduced by Deirmendijan (1969), Kattawar and Plass (1967), and Wiscombe(1980). A modern explanation of Mie theory is given, for example, by Bohren and Huffman (1983). For more detail on the program, as well as for potential applications, please refer to the program help file.

You may also want to consider companion graphical data viewing spreadsheets.

Please also inquire how we can modify the calculator and/or the companion products to better suit your specific needs.

Program control panel

The screen shots of the program control panel are shown below (the actual panel form may differ due to a continued improvement and enhancement of the program capabilities and user interface):

MjcLscHomoSph control panel - single-particle mode
A single-particle mode.

[Menu]

MjcLscHomoSph control panel - integration mode
A particle-size integration mode. In this mode the scattering properties, weighed by a particle size distribution, can be integrated over a particle size range, as defined in the diameter range specification, next to the Edit diam button.

Input data

The user manually enters required data in edit boxes of the main form.
[Menu]

Output data

The output data can be arranged by the user in several formats as functions of:

  • scattering angle
  • particle size

Please see the program help file for details. The output can be viewed as text, saved to a text file, or copied to the Windows clipboard for pasting into a spreadsheet (see also companion products).

Graphical data viewers

Companion spreadsheets in Microsoft ExcelTM (available separately) simplify viewing in graphical, publication-ready form of:

  • angle-dependent patterns
  • particle size-dependent patterns

The spreadsheets (requiring Microsoft Excel or a compatible spreadsheet program) feature time-saving data manipulation macros. In particular these spreadsheets permit convenient graphical comparison of data with reference data. Please see detailed screen shots. The spreadsheets may be modified by the user to the full extent permitted by Microsoft Excel.
