Study of dynamic scalar potential

Going on trying to find the conditions at which the standing waves will form in the near field, we can study the pattern of radiation of dipole in which the charges vary in phase, and the more, in which the between-charges distance is equal to the radiation wavelength. In this case the diagram of dynamic scalar potential will take the form shown in Fig. 10.

Fig. 10. Diagram of dynamic scalar potential of in-phase dipole with the length equal to the radiation wavelength

In this diagram we see that the spatial distribution of scalar potential has complicated. The maximum of radiation goes towards the line of charges, which is quite expectable for the dipole length equal to the radiation wavelength with synchronous charge variation. In the region of normal to the line of charges we also see the maximum of longitudinal radiation with some transition region to the region of radiation along the line of charges. But there also is not a standing wave.
