Helicity and duality symmetry in light-matter interactions
Par Ivan Fernandez-Corbaton, Karlsruhe Institute of Technology
Lundi 10 Octobre, 11h, Salle des séminaires (215), 2ème étage, Bâtiment A4N
My research has been revolving around the use of electromagnetic helicity and electromagnetic duality in light matter interactions. I use this pair in the general context of exploiting the symmetries of the scattering operators of the objects of interest. In my talk, I will give an overview of the framework and then speak about some results that I have obtained using it. For example, insights in optical activity, generalized zero back-scattering conditions, and a robust definition of electromagnetic chirality. I will then speak about future work, where I wish to use symmetry derived guidelines for the design of nanostructures with particular light-matter interaction properties.
