This program implements the generalized 4x4 transfer matrix (GTM) method poposed in Passler, N. C. and Paarmann, A., JOSA B 34, 2128 (2017) and corrected in Passler, N. C. and Paarmann, A., JOSA B 36, 3246 (2019). A Matlab code can be downloaded on zenodo.

As of March 2020, it furthers implements the layer-resolved absorption method proposed in Passler, N. C., Jeannin, M. and Paarmann, A., A Matlab code is also available for this update on zenodo.

This Python implementation also relies on inputs from D. Dietze's FSRStools code https://github.com/ddietze/FSRStools

You should be able to install using pip install . or running python setup.py install, from the project root directory. Otherwise just copy the GTM folder somewhere where python will find it or add the path to your PYTHONPATH variable.

Prerequisite: NumPy, SciPy, Matplotlib
