ADDA: Open-Source Light Scattering Simulation Software
Software for simulating light scattering from particles and surfaces, calculating scattering properties like cross sections and Mueller matrix elements
What is ADDA ?
ADDA is an open-source software package for simulating light scattering by particles and surfaces. It can accurately compute optical properties like scattering and extinction cross sections, Mueller matrix elements, and more for a wide range of particle shapes and structures.
For individual particles, ADDA can handle spherical particles, clusters of spheres, arbitrary shapes imported from CAD software, and more. It implements state-of-the-art methods like the discrete dipole approximation, T-matrix method, and boundary element method to solve Maxwell's equations for scattering.
ADDA can also simulate periodic structures like gratings and crystals. The software implements rigorous coupled wave analysis and Fourier modal methods for periodic structures. It can account for complex materials and rough surfaces.
Some key features and capabilities:
- Open-source software under GPL license
- Simulations for individual particles and periodic structures
- Various particle shapes: spheres, clusters of spheres, imported geometries, periodic arrays
- Several computational methods: DDA, T-matrix, BEM for particles; RCWA, FMM for periodic structures
- Arbitrary material dispersion
- Near-field and far-field computations
- MPI parallelization for efficient computations
With its rigourous computational techniques and open-source nature, ADDA is a useful tool for researchers and engineers working on scattering-related optics and photonics problems.
