Electromagnetic modeling of finite length wires buried in a lossy half-space. (English) Zbl 0995.78041

Summary: The horizontal buried wire of a finite length is analyzed by using the scattering theory. The current distribution along the wire due to an external electromagnetic interference source is governed by the half-space Pocklington integral equation. The effect of the lower halfspace is taken into account via the transmission coefficient (TC) appearing within the integral equation kernel. The principal advantage of the TC approach vs rigorous Sommerfeld integral approach is the formulation simplicity and reduced computational cost. The variational boundary element procedure is used for solving the Pocklington integral equation and the current induced along the buried wire due to the transmitted plane wave or current source excitation is obtained.
