RETOP
RETOP is an free Matlab toobox that implements a near-to-far-field transformation for computing the radiation diagram. RETOP operates for objects on substrates or buried in stratified media.
PyMieLab
PyMieLab can calculate optical parameters including far-field and near-field parameters. PyMieLab provides a particle refractive index database with 2841 sets of experimental data for 370 materials. PyMieLab has a friendly GUI with many interactive menu bars, tools, and buttons.

Magnetic sphere
FORTRAN code printed in the report Milham, Merill E.: Electromagnetic Scattering by Magnetic Spheres: Theory and Algorithms. Edgewood Research Devellopment and Engineering Center Aberdeen Proving Ground MD, ADA289798, 1994-10-01.
Fortran 95 Mie Theory Library
The library explicitly defines the spherical Bessel functions and associated Legendre polynomials. The library is optimized to the extent of removing extraneous variables and
combing loops to reduce the total number of iterations, and using Gfortran compilation options and constraints.
TransitionMatrices.jl
The Julia package `TransitionMatrices.jl` by Zihua Wu implements the classic EBCM method, supporting arbitrary precision and automatic differentiation. To calculate the T-Matrix of various types of scatterers the EBCM and the Invariant Imbedding T-Matrix Method (IITM) is implemented.
Beyond Mie Theory
Matlab code for systematic computation of bulk scattering parameters based on microphysical wave optics.
Scattering Dynamics
scadyn is a code for scattering dynamics calculations, which utilizes a volume integral equation solution to compute the T-matrices of non-spherical scatterers (T-VIE) .
JaSTA-3
Java superposition T-matrix Application: version-3.0
Multipole Decomposition
Multipole Decomposition comming with PyGDM. The formalism allows calculating the extinction and scattering spectra of arbitrary shaped nanostructures.
CosTuuM
An open-source C++-based Python library CosTuuM that can be used to generate infrared absorption and emission coefficients for arbitrary mixtures of spheroidal dust grains that are (partially) aligned with a magnetic field.
