domna/pyelli repository overview

Github repository⁠

PyElli is an open source numerical solver for spectral ellipsometry employing well-known 2x2 and 4x4 algorithms. It is intended for a broad case of problems including simple fitting of layered structures, anisotropic layers and any other light interaction with layered 1D structures. It serves as a system for the day to day ellipsometry task at hand and is easily extendable with your own dispersion models, EMAs or solvers. Our goal is to provide a reproducible and flexible tool for the needs of scientists working with spectral ellipsometry.

⁠Features

• A multitude of models to approximate the dielectric function of your material.
• Build up your structure easily from materials and layers.
• Simulate reflection and transmission spectra, ellipsometric parameters and Mueller matrices.
• Utilities to quickly convert, plot and fit your measurement data.
• Powerful when necessary, editable and expandable.
