WG2 - Theory and modelling

This Working Group highlights the theoretical foundations of polarized radiation, as well as its numerical modelling as the essential link between theory and spectro-polarimetric observations. Therefore, it addresses the complex physics of the interaction of radiation and matter in magnetized plasmas, as well as the generation and transfer of polarized radiation. It deals also with the development and implementation of efficient numerical methods for making feasible realistic numerical simulations, as well as with polarized radiation diagnostics for determining the geometry and/or the physical properties of the astrophysical system under investigation.
