Electromagnetic scattering from a coated notched cylinder

Abstract

The problem of electromagnetic scattering of a normally incident plane wave from a coated conducting notched cylinder is solved. The coating material and the notch material are arbitrary dielectrics, and the incident wave is either transverse electric or transverse magnetic polarized. The numerical results of backscattering cross-section calculations are presented, and the dependence of the cross section on the various physical parameters is investigated. The coated notched cylinder system possesses characteristic electromagnetic resonances that manifest themselves in the scattering spectra.
