Radiation & Non-Radiation Terms in Equation B for Moving Charged Particle

[f16842000]

What is the radiation and non-radiation terms in the equation B for a moving charged particle. How can I express the result in a tensor form?

Thanks!

Good question. 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.
