(Moreover, by the condition of the field calculation r >> l , consequently, r does not vanish, as it exceeds the limits of solution reliability). Proceeding from that, (2-3-10) has to take a normal form |

(33) |
As we can see, (33) describes the progressive wave; it means that the longitudinal component of the field r has, none the less, the wave nature, and in the view of progressive nature of wave propagation it is illegitimate to divide the field of radiator into the near and far fields. Both in the near and far fields the wave is progressive. One would think: having determined such important characteristic, we can consider the Pointing vector for a longitudinal wave: |

However here we are running into a double complication caused again by the invalid simplifications and omissions. First, if we try substituting the corrected system (33) into the system of Maxwell equations, this will not work because of phase shift by /2 between (t - r) and (t - r) . For example, when substituting (33) into the equality | |
in the left-hand part of the sum the uncompensated term | |
appears, and it must be equalised to zero with all consequences. Given the derivation of field equations, conducted by Kugushev and based on the standard field theory formalism, coincides in its technique with that conventional, the incorrectness of simplifications was caused not by the author's inattention but it was a compulsory action to retain the structure of the formalism based on Maxwell's equations. This conclusion can be corroborated simply by way of analysing the second pair of Maxwell's equations 41 |

by analogy with the pair of Maxwell's equations | |
S econd, the vectors r and anyway must not be combined, because was created by way of variation of , i.e., of the transversal wave vector. So for the Pointing vector |

is true. The vector of the magnetic field strength ? created by r was not present in the consideration at all, though, as we pointed above, according to Maxwell's equations, |
|
and if r had the wave pattern, ? must exist and must have the form of solenoidal vector around the force lines r (see Fig. 3). ? was absent in the consideration just due to its axial nature, because conventionally the only component of magnetic field is a linear vector. |
