If you want to know the energy flows, you can compute the stress-energy tensor and the Poynting vector as in https://en.wikipedia.org/w/index.ph...26693874#Electromagnetic_stress–energy_tensor That will describe the distribution (stress-energy tensor ##T^{ab}##) or flow (Poynting vector , ##S^a = T^{ab} u_b##), ##u_b## being the 4-velocity of the observer ). I don't know how to separate out the radiation part, alas.
