Scattering from Dielectric Cylinders Buried in a Two-Layer Lossy Earth

The present paper is an extension of previous scattering analyses, using a particular two-layer model for the structure of the ground. The scattering of a plane wave incident on the earth due to a buried cylinder is considered using an integral equation approach. The resulting integral equation is solved for the unknown electric field inside the scatterer. Further, the scattered field in the air is evaluated through the integral equation employing the method of steepest descent. Numerical results concerning the various parameters of the problem are obtained and compared with similar results of relative papers.
