# Multi Spheres T-matrix Studio¶

Python wrapper for multiple sphere T-matrix (MSTM) code and Mie theory to calculate surface plasmon resonance (SPR) spectrum and fit it to experiment.

## Features¶

- Materials defined from constant expression, from tabulated file or from analytical formula of Rioux et al for Au-Ag;
- Simple functional contributions (linear, lorentzian, gaussian)
- Mie theory contributions
- MSTM calculations: spectra and near-field intensity
- Fitting of experimental data by any of the mentioned contributions, including combinations
- Interactive graphical user interface
- Flexible Python scripting
