TREAMS

TREAMS is an open-source program to perform T-matrix-based scattering calculations for nanophotonic systems. It focuses on efficiently solving the interaction in 1D, 2D, and 3D lattices of complex unit cells using quickly convergent lattice sums. It also solves the interaction in finite clusters.

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

If you're using the system wide installed version of python, you might consider the --user option.
