C++ object class library (SCATMECH) to disseminate simple models for light scattering from smooth surfaces. The library includes routines for scattering from spherical particles (Rayleigh, Rayleigh-Gans, and Mie) and routines for various models of scattering from surfaces. Data types for manipulating different representations for the polarization of light and the polarimetric properties of materials,specifically Mueller matrices, Stokes vectors, and Jones matrices and vectors.
