On the Electromagnetic Radiation from a Short Electric Dipole According to the Rotary Theory

Abstract

The paper is dedicated to a basic question, connected with the Maxwell’s classical electromagnetic theory, concerning the electromagnetic wave equations and their meaning. Rotary theory appeared after 1998 and it introduced new terms about the basic quantities of the electromagnetic field - the vector of the magnetic field intensity \( \vec{H} \), the vector of the magnetic flux density \( \vec{B} \) and some others, presenting them as moments of the vector of the current density of the tangential displacement current \( \vec{j}_{{D_{\tau } }} \), claiming in this way that the magnetic field is a form of a rotating electric field around the moving charges. The final result is a set of electromagnetic equations in a fully electrical form, reaching a new model of propagation of the electromagnetic wave in free space, different from the classical one. In this way rotary theory gives a new possibility to explain what kind of object is the electromagnetic wave. The concrete investigation is concerned with the electromagnetic wave, which is radiated from elementary electric dipole antenna (taken as an example for simplicity of the extraction of the new equation of the electromagnetic wave). By the help of the method of moments, the \( \vec{H} \)-wave equation is turned into a wave equation of the vector \( \vec{j}_{{D_{\tau } }} \), which also obeys to Ohm’s law in differential (point) form, proving the fact that the propagation of the electromagnetic wave is really a process of flowing of the displacement current in space. That confirms the statement, that the electromagnetic processes in nature have only electrical origin.
