Abstract
As is well known, time-independent fields generated by dielectric and magnetic materials can be described by real polarization charges and fictitious magnetic charges, respectively. In addition, magnetic materials can also be studied by means of real currents, but no equivalent-current formulation has been given for dielectric materials. In this paper, a compact formulation of Maxwell equations is presented which shows that it is possible to treat time-independent fields generated by dielectric media by using fictitious ‘‘currents’’ related to the electric polarization vector. This compact formulation shows that a complete analogy can be drawn between dielectric and magnetic phenomena.
