Multipole radiation fields from the Jefimenko equation for the magnetic field and the Panofsky-Phillips equation for the electric field

摘要

We show how to obtain the first multipole contributions to theelectromagnetic radiation emited by an arbitrary localized source directly fromthe Jefimenko equation for the magnetic field and the Panofsky-Phillipsequation for the electric field. This procedure avoids the unnecessarycalculation of the electromagnetic potentials.
