Rigorous Approach to Analysis of Backscattering from 2D Open-Ended S-shaped Cavities

The problem of the scattering of an E-polarized plane wave from 2D open-ended S-shaped cavities is rigorously solved by the Method of Analytical Regularization. The obtained solution is used for full-wave analysis of backscattering. The special focus is on studies of resonance phenomena observed in the spectral dependence of the Radar Cross Section. They are explained as excitation of the complex natural oscillations in S-shaped cavities.
