Abstract

We investigated the Onsager relations in the context of electromagnetic constitutive relations of linear, homogeneous materials. We determined that application of the Onsager relations to the constitutive equations relating #P and #M to both #E and #B is in accord with Lorentz reciprocity as well as the Post constraint.
