As an example of this method to visualise the fields, in Fig. 5 we show the dynamic pattern of scalar potential of dipole, when the length of dipole is equal to a half of wavelength. |

Fig. 5. Dynamic pattern of dipole potential distribution with the dipole length equal to a half of wavelength |
In this diagram, the sources are positioned in parallel to
the axis x, separation into the scalar and vector potentials is absent, because, as
we said before, the vector potential results from the transformation of gradient of scalar
potential in dynamic fields. None the less, affection of the vector potential on diagram
formation is obvious, as it reveals every time when the delay phases appeared. We see in
the diagram that radiation consists of two semi-spherical waves propagating from dipole
and shifted relatively each other by the phase equal to From this immediately follows the conclusion made in [1] that in the transverse wave the curl of gradient of scalar potential is not zero. |
