“…This problem is solved in [25] by the Integral Equation Method and in [26] by the Eigenfunction Expansion Method. The RCS (σ/λ) of this structure obtained by the proposed method of addition theorems and those computed by the methods in [25] and [26] agree very well as depicted in Fig. 2 for the angle of observation from 'ϕ = 0 to ϕ = π' for both TE and TM polarizations.…”

Abstract-The addition theorems are applied to analyze the normal incidence of plane waves onto infinitely long conducting or dielectric circular cylinders with multilayer coatings made of common and uncommon materials (ε r , µ r , σ) with the objective of minimization and maximization of radar cross-section (RCS). TE, TM and circular polarizations of the incident wave are considered. Optimization of RCS by the method of least squares leads to the determination of layer thicknesses and the material complex permittivities and permeabilities. A sensitivity analysis of RCS with respect to the geometrical and material parameters of the multilayer coated conducting cylinder is also performed. It is observed that broadband reduction of RCS is mostly achievable by a combination of conventional materials (ε r , µ r > 1), and unconventional materials (0 < ε r , µ r < 1) and lossy materials (σ > 0). It is seen that RCS reduction is due to the diversion and dissipation of radar signals. The results agree very well with the experimental and theoretical data available in the literature.

“…A given approach is assumed to be convergent if {k} → 0 , as k → ∞ . In order to apply the distorted-wave Born approximation, at the first iteration step, the field Ψ L (r ) is numerically computed by the Richmond formulation [12], which has been proved to be accurate for forward-scattering by dielectric cylinders, if a TM illumination is used. The cross-section S is partitioned into P subdomains, p = 1, .…”

Abstract-An approach based on the use of the arithmetic of intervals and Interval Analysis for the solution of inverse scattering problems is presented and assessed. By exploiting the property of the Interval Analysis to find the global minimum of a functional in a n-dimensional space, the proposed approach adopts a branch and bound process to discard the regions of the solutions space not containing the global solution, while keeping those where a feasible solution is expected until a suitable converge criterion is reached. A representative set of results concerned with the reconstruction of circular dielectric objects within the first-order Born approximation are reported and discussed to show potentialities and current limitations of the proposed approach.
