 PF Gold P: 4,087 The SET of the EM field is $$T^{\mu\nu} = F^{\mu\alpha}F^\nu_\alpha - \frac{1}{4}g^{\mu\nu}F^{ab}F_{ab}$$ where F is the field tensor. It's explained better here http://en.wikipedia.org/wiki/Electro...-energy_tensor and the solution of the EFE is the electro-vacuum http://en.wikipedia.org/wiki/Electrovacuum_solution
