Scattering of E-polarized electromagnetic wave by dielectric-coated axially slotted cylinder

The rigorous solution of the problem is presented. The boundary-value method is employed using the property of completeness of angular functions on the respective intervals. The scattered far-field (SFF) and back radar cross section (BRCS) of the structure are evaluated asymptotically. The scattered field characteristics in the case of an E-polarized plane wave are analyzed numerically with controlled accuracy. It is shown that a resonant increase of BRCS is observed when the cylinder is filled with dielectric.
