Image and Exact Models of a Vertical Wire Penetrating a Two-Layered Earth

  title={Image and Exact Models of a Vertical Wire Penetrating a Two-Layered Earth},
  author={Vesna Arnautovski-Toseva and Leonid Grcev},
  journal={IEEE Transactions on Electromagnetic Compatibility},
In this paper, we investigate the validity of image theory in modeling a vertical wire penetrating a uniform or two-layered earth. First, a rigorous full-wave electromagnetic model is described that may be used as a standard for comparison. The model is based on the method of moments (MoM) and exact Green functions for the layered earth that involve Sommerfeld-type integrals. Next, we derive the image model from the exact model and analyze the approximations. We compare the current along a… CONTINUE READING
