abstract={When studying the energy principle of N current elements, the author found that the Poynting¡¯s theorem of N current elements is very similar to the principle of mutual energy, except that the subscript of the summation symbol is different. Because the mutual energy principle of N current elements and Poynting¡¯s law of N current elements are all energy conservation laws, the author considers that they should be the same. Due to this consideration, the author found that the self-energy flow should not transfer energy. Self-energy flow is the energy flow corresponding to the Poynting vector of a current element, but this energy flow is not zero for any antenna. The author believes that this is a loophole in classical electromagnetic theory. The author¡¯s previous solution was to add a time-reversal wave to Maxwell¡¯s theory. This paper studies this problem through the electromagnetic field of plane-sheet current. It is found that the magnetic field calculated by Maxwell¡¯s equations is still the magnetic field generated by the current itself, but the electric field calculated by Maxwell¡¯s equation is actually the advanced wave generated by the environment of the current.},
