"Periodic T-matrix scattering algorithms"
Project description
treams
The package treams provides a framework to simplify computations of the
electromagnetic scattering of waves at finite and at periodic arrangements of particles
based on the T-matrix method.
Installation
Installation using pip
To install the package with pip, use
pip install git+https://github.com/tfp-photonics/treams.git
If you're using the system wide installed version of python, you might consider the
--user option.
Running on Windows
For Windows, there are currently two tested ways how to install treams. The first option
is using the
Windows Subsystem for Linux (WSL).
Within WSL treams can be installed just as described above. The second option, that was
tested is using MSYS2 with the mingw64 environment.
Likely, other python versions based on mingw-w64 might also work.
