Light scattering calculator: coated sphere (MjcLscCoatSph)
The MjcLscCoatSph light scattering program calculates an
angular scattering pattern as well as scattering, absorption, and attenuation
parameters of a single coated sphere (core-shell sphere) according to the Aden/Kerker theory as
modified by Toon and Ackerman (1988) and by Miroslaw Jonasz.
You may also want to consider purchasing the
following companion products:
- A spreadsheet in MS Excel™ for viewing
and archiving scattering patterns (|S1|2, |S2|2, and M11) as functions of the scattering angle (VAP)
- A spreadsheet in MS Excel™ for viewing
and archiving integral parameters of the particle (attenuation, scattering, and absorption efficiencies, and three scattering functions: |S1|2, |S2|2, and M11 at a fixed scattering angle) as functions of the particle size (VSP)
Both viewers also calculate and display in graphical form the polarization factor, defined as -M12 / M11, where Mij are elements of the scattering (Mueller) matrix.
Please also
inquire
how we can modify the calculator and/or the companion products to better fulfill
your specific needs.

The user manually enters required data in edit
boxes of the main form. For more detail
please refer to the program help file (or

The output data can be arranged by the user as functions of:
- scattering angle, theta
(with a constant particle size and constant fractional coating thickness)
The program calculates |S1|2, |S2|2, and S11 as functions of theta. The program also calculates efficiencies, cross sections (where applicable), and Mie factors for attenuation, scattering, and absorption.
- particle size
The program calculates the attenuation, scattering, and absorption efficiencies, and three scattering functions: |S1|2, |S2|2, and M11 at a fixed scattering angle as functions of x or the absolute particle diameter. The following options are possible:
- variable particle (i.e. shell) size, constant shell thickness
- variable particle (i.e. shell) size, constant fractional (ratio) shell thickness
- variable particle (i.e. shell) size, constant core size
- constant particle (i.e. shell) size, variable fractional (ratio) shell thickness (0-0.999999)
- wavelength of light (in the medium surrounding the particle), λ (with a constant particle size, constant fractional coating thickness, and user-supplied wavelength-dependent complex refractive indices for the core and coating(shell))
The program calculates the attenuation, scattering, and absorption efficiencies, and three scattering functions: |S1|2, |S2|2, and M11 at a fixed scattering angle as functions of x.
The particle size can be specified as follows:
- relative size, x = PI D / λ, where D is the particle diameter and λ is the wavelength of light in the medium surrounding the particle
- absolute particle diameter, µm
The output can be
viewed as text, saved to a text file, or copied to the Windows clipboard for
pasting into a spreadsheet. Companion spreadsheets in MS ExcelTM (available separately, please see the order info) simplify viewing in graphical
form (ready for exporting to a report) of:
- angular scattering patterns
- integral parameters (attenuation, scattering, absorption, scattering at a fixed angle) as functions of the particle size.
