September 2021: Phenomenological interpretation of Mueller matrix polarimetry results: theory and experiment, presented by Razvigor Ossikovski
Each month, speakers explore topics derived from Henri Poincaré’s work on optical polarization and demonstrate applications of polarization techniques. This month's title is Phenomenological interpretation of Mueller matrix polarimetry results: theory and experiment, presented by Razvigor Ossikovski.

Join the series’ chairs and moderators – Thomas A. Germer, National Institute of Standards and Technology (USA); Jessica C. Ramella-Roman, Florida International University (USA); and Tatiana Novikova, École Polytechnique (France) – and be part of the discussion.

Tuesday, 28 September 2021, 6:00 am PT (1300 UTC): Phenomenological interpretation of Mueller matrix polarimetry results: theory and experiment
Speaker: Razvigor Ossikovski
Ecole Polytechnique, Institut Polytechnique de Paris (France)

Abstract: The availability of easy-to-use polarimetric equipment has made possible the routine study of a wide range of complex materials and provides a large amount of data, in the form of Mueller matrices, to experimentalists. The problem of the physical interpretation of a measured Mueller matrix is thus of growing importance. In the absence of an electromagnetic model describing it, an experimental Mueller matrix can still be phenomenologically interpreted by decomposing it algebraically into simpler components with straightforward physical meaning. The purpose of the present talk is to introduce several algebraic methods in use and to illustrate them on experimental examples.
