Electromagnetic media are modelled through linear functionals of the history of the electric and magnetic fields. Detailed thermodynamic restrictions are derived for the tensor-valued coefficients and kernels occurring in the functionals. A connection with the Kramers-Kronig relations is established
In the first part of this paper, the relativistic significance of the projective curvature tensor Wh<jk is discussed. It is found that the vanishing of the divergence of this tensor in an electrovac universe implies a purely electric field. By breaking Whijk into its antisymmetric and symmetric part
