Unformatted text preview: March 17 09 Lecture Notes Page 1 8.7.3 Electromagnetic Fields Define anti-symmetric: Components of a) b) With the basic relativistic formulation done, we now turn our attention to the secondary, derived quantities, namely electric and magnetic field, energy density, Poynting Vector, Stress Tensor . . The idea is to find direct relationships for these quantities without having to go through the vector potential for which we already know the transformation behavior. Lecture Notes Page 2 8.7.4 Energy-Momentum Tensor symmetric: (u: energy density) (Poynting vector) Maxwell-Stress Tensor Proof: clear for term Now term Components: Lecture Notes Page 3...
