Short-Pulse Electromagnetic Scattering by Buried Perfectly Conducting Cylinders

In this letter, the electromagnetic scattering problem of a short-pulse plane wave by a finite set of buried perfectly conducting circular cylinders is addressed in the time domain. The described procedure is applicable for arbitrary polarization and for any cylinder size and configuration in both near- and far-field regions. The solution is performed through an angular-spectrum representation of the scattered field. A parametric analysis on the effects of the various geometrical parameters is reported, and numerical results are presented.
