Electromagnetic Fields Generated by the Lightning Channel The radiation and static terms in Equation (8a ) comply with straight in the above two equations A15 and A16 once the equations are reduced for the situation that dz is infinitesimal and summing up the contribution from each of the channel elements by performing the integration along the channel. On the other hand, let us keep the above equations inside the existing type and replace the integration along the channel by a summation. Let us take into account the radiation field. When we take the summation beginning from the very first element located at the bottom from the channel, one particular can see directly that the radiation coming from the best on the very first element will likely be cancelled off together with the radiation coming from the bottom of the second element, the radiation coming in the best in the second element might be cancelled off using the radiation coming from the bottom with the third element, and so forth. As a result, at any point in space, only the radiation term coming in the bottom in the first element will survive(A16)Atmosphere 2021, 12,13 ofduring the summation. Hence, the radiation field at the surface of a perfectly conducting ground is offered by v i (t – z/v – d/c) erad = – az . (A17) d 2 o c2 Observe that within the above case, r1 D , sin 1 along with a -az . This Lupeol acetate really is identical for the radiation field in Equation (9a ). Now, let us contemplate the static term. As within the radiation field, once you take the summation, only the term corresponding for the bottom with the first element will survive. Even so, when we take into account the fact that the lightning channel is positioned above a completely conducting ground, this static term will cancel off with the corresponding term related with all the image of the element inside the perfectly conducting ground plane. Therefore, the total static field will grow to be equal to zero. That may be, estat = 0. (A18) This evaluation shows that all of the terms of Equation (8a ) are identical for the corresponding terms in Equation (9a ) and that these two equations are identical to each other. Just to illustrate this further, we’ve calculated the electric field at one hundred m distance from a lightning channel applying Equations (8a ) and (9a ). The unique elements and also the total field obtained from Equations (8a ) and (9a ) 15 depicted in Figure A2. Note which can be 14 of as illustrated above, the 3 field terms are identical in both formulations.Atmosphere 2021, 12,(a)(b)Figure A2.
