snompy: a package for modelling scattering-type scanning near-field optical microscopy
Tom Vincent, Xinyun Liu, Daniel Johnson +5
Scattering-type scanning near-field optical microscopy (s-SNOM) is a powerful technique for extreme subwavelength imaging and spectroscopy, with around 20 nm spatial resolution. Bu…
