Description: The one-loop radiative correction to the photon propagator can be graphically represented by the Feynman diagram of the second order. The physical meaning is that photon can exist in the intermediate state with the electron and positron as virtual particles. The photon propagation function based on such process with electron-positron pair is derived. The modified Lagrangian of electromagnetic field is derived supposing the modified photon propagator. The Schwinger source methods of quantum field theory was applied. Then, the modified Maxwell equations are derived from the new Lagrangian.
