A System-by-Design approach for the synthesis of multi-layer mantle cloaks

The problem of designing a multi-layer mantle cloak suitable for large dielectric cylinders is addressed through an innovative System-by-Design-Scattering Cancellation (SbD-SC) procedure. More in detail, the minimization of the overall Scattering Cross Section (SCS) is obtained by adjusting the multi-layer cover parameters (i.e., surface impedances and radii) so that both the fundamental and the higher order scattering modes are canceled. The arising design problem is solved through an instance of the SbD paradigm, which is adopted to effectively and efficiently explore the solution space. The features of the proposed SbD-SC technique are illustrated through a preliminary numerical example.
