strapy - scattering and transfer matrix model, python

strapy is python package implementing the combined transfer and scattering matrix modelling approach described in [1], jointly developed by the National Physical Laboratory and the Centre for Engineering Photonics at Cranfield University as part of an EPSRC funded iCASE studentship. The primary motivation to develop this software was to model the effects of multiple reflections and polarisation leakage within the optics of homodyne displacement measuring interferometers, however strapy is generally applicable to modelling the propagation of monochromatic light through networks of planar optical components.
