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 treams
This will make sure to also install all required dependencies (i.e. numpy and scipy). Please ignore the requirements.txt, as they only serve to instruct binder which packages to install to run the documentation notebooks interactively.
If you're using the system wide installed version of python, you might consider the
--user option.
