Continuing the contribution about “wireless power transmission by scalar waves”, presented in Moscow 2012, the paper from PIERS Stockholm 2013 goes deeper, explaining the different types and properties of waves described by the wave equation. Starting with the wave description of Maxwell an extended version of the Laplace equation is derived, expanding the standard derivations of the near field, showing how to influence the zone, where the longitudinal wave parts occur. We come to the conclusion that the near field zone is enlarging, if the longitudinal parts of a wave or the antenna voltage are accelerated. This relationship is essential for the wireless transmission of energy. In addition this exciting new result could be tested experimentally. The simple experiment has been demonstrated more often. Only by changing the antenna design, it was shown how both, the speed of propagation and the near field are enlarging proportional to each other. In all practical applications, as discussed in different congress Proceedings, the extended near field is the key of success. This paper contents the calculation of the transition from near field to far field of an antenna, resp. from field vortex propagation, as a so called scalar wave, to an electromagnetic wave.
