Abstract
Using a Green's function approach, similar to that used to treat scattering from underground tunnels, the problem is considered of electromagnetic scattering from conducting wires buried in the earth. The method leads to an integral equation for the unknown surface current J(ř) of the conducting cylinder. The expansion of J(ř) in terms of surface cylindrical wavefunctions and substitution in the integral equation results in an infinite set of linear equations for the unknown expansion coefficients. An effective truncation algorithm has been employed to evaluate these coefficients and, afterwards, the scattered field. Numerical results for the far-field region of the buried scatterer are plotted and some useful conclusions based on them are discussed.
