pyElli 0.9.1

Python implementation of Berremans 4x4 matrix method

pyElli

PyElli is a 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 makes fitting a breeze.

Features

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

How to get it

The installers for all releases are available at the Python Package Index (PyPI).

To install run:

pip install pyElli

A complete environment for pyElli is also available as a Docker Container. From a running Docker installation simply run:

docker pull domna/pyelli

The source code is hosted on GitHub, to install from source run:

python setup.py install
