ACCURATE BACKSCATTERING STUDIES FOR DOUBLE-LAYERED ARRAY OF INFINITELY LONG CYLINDERS

摘要

The two-dimensional Helmholtz equation with Dirichlet's boundary conditions is rigorously solved for multiple arbitrary profiled cylinders. This describes the wave diffraction of E-polarized electromagnetic field. The developed algorithm is used for calculation of the radar cross-section of an infinitely long double-layered array. In this article, we focus on the resonance response of the structure caused by excitation of the high Q-factor oscillations.
