Induction characteristic of an equipment with the grounding wire using wire-grid approximation

In this paper, equipment with grounding wire is approximated by a wire-grid model and the method of moment is applied to evaluate induced current and electromagnetic field distribution near the equipment. Consequently, it is confirmed that the induced current on the grounding wire oscillates at a frequency which one fourth of wavelength is equal to the model's three dimensions sum. Moreover, the electric field near the model varies largely depending on the current induced on the grounding wire.
