In general explanation for propagation of electromagnetic wave at a plane between two media of different dielectric properties. The description of this phenomenon be based on the actual physical process of the well know interpretation of the classical rays with the polarization vectors. In this research, we investigate this situation by using the knowledge of the amplitude of emission and absorption of massless spin-1 particle (photon) excitation by the emitter and detector, respectively. By using time evolution process based on vacuum-to-vacuum transition amplitude in quantum (field) theory QED formalism. This process shows that the propagation of photon excitation by the external sources is given with an explanation of the amplitude of propagation between different spacetime points from an emitter to a detector, which exclude with the Feynman propagator. The purpose of this research is developing a formalism based on the actual physical process of photons propagate from an emitter to a detector. It shows the consistency to the actual physical process of interpretation of the polarization vectors in the classical rays.
