Spacetime metric from linear electrodynamics

Abstract

The Maxwell equations are formulated on an arbitrary (1+3)-dimensional manifold. Then, imposing a (constrained) linear constitutive relation between electromagnetic field $(E,B)$ and excitation $(\mathcal{D},\mathcal{H})$, we derive the metric of spacetime therefrom.
