Analysis of magnetic fields radiated by lightning strikes to a building

Almost all modern buildings use steel mesh, when a large current occurs nearby, such as a lightning return stroke happens, for the law of electromagnetic induction, electromagnetic fields generated by the lightning would certainly be affected. In general case, lightning detection stations are generally placed near the buildings, so the received signal would be affected by the buildings nearby. In this paper, we use FEKO to make geometric models of buildings, with MOM method to calculate whether or how the buildings impact the lightning magnetic field radiation.
