Functional Approach to Electrodynamics of Media — •Ronald Starke1 and Giulio Schober21Institut f. Theo. Physik, Bergakademie Freiberg — 2Institut f. Theo. Physik, Uni Heidelberg

We put forward a new approach to electrodynamics of materials allowing us to derive universal (material-independent) relations between electromagnetic response functions such as the dielectric tensor, the magnetic susceptibility and the microscopic conductivity tensor. Our formulae include all effects of inhomogeneity, anisotropy, magnetoelectric coupling and relativistic retardation. Moreover, we relate the 36 component functions of the constitutive tensor used in the context of bi-anisotropic media to only 9 causal response functions which specify the current response to an external vector potential.
