User guide

This is the user guide for the Python package snompy, which is an implementation of the finite dipole model (FDM) and the point dipole model (PDM) for predicting contrasts in scattering-type scanning near-field optical microscopy (SNOM) measurements.

Here we provide examples of how to use this package, along with an explanation of how the models are implemented. You won’t need a detailed understanding of the FDM or PDM to understand this guide, but it’ll be helpful to know the basics of SNOM and atomic force microscopy (AFM). For more detailed documentation of the functions provided by this package, see API reference.
