Web6.2.2 Polarization. Currents create vector potentials in the same direction as the current flow. The resulting electric field is constructed from the part of the vector potential that is perpendicular to the direction of propagation. A simple antenna like a dipole, which has current flowing only in one direction, creates a linearly-polarized ... Webcan be deduced from the retarded vector potential, by consideration of the boundary con-dition that the tangential component of the electric field must vanish at the surface of a good/perfect conductor. ... and so the vector potential along the antenna is, Az(0,0,z) ...

In the following section the retarded 4-vector potential is derived from inhomgeneous d’Alembert equations and the Lorenz condition. The reason for the difference between the potential so-obtained and the pre-relativistic LW potentials is explained. In Section 3 Feynman’s derivation of the LW ... major principles of psychodynamic theory
