Two-dimensional electromagnetic scattering from an underground cylinder is the foundation of underground EM prospecting. The conventional procedure employing the boundary integral equation method and spectral domain technique is very complicated
it is inconvenient for the enginnering application.In this paper
a new procedure
generalized equivalent sources method in spectral domain
is proposed.The scatterer is substituted by a set of appropriate generalized equivalent sources for avoiding the boundary integration
and the Sommerfele’s integrals are simplified by use of a convergence accelerating technique.The formulations for analysing the scattering from an underground cylinder are given and utilized in several examples.
