Recent developments in the design of microwave mantle cloaks with improved performance and relative applications

In this contribution, we present our latest results concerning the design of microwave mantle cloaking devices and show some of their applications in different operative scenarios. We start by describing the analytical models of the anisotropic metasurfaces needed to achieve a scattering cross section (SCS) reduction for any polarization of the incident field and, then, we prove the effectiveness of these formulas in a representative antenna scenario. Finally, we show that the proposed formulas still hold in the case of multilayered cloaks that, being able to tailor different scattering modes excited by an object, can be successfully used to cloak non-electrically small objects and/or achieve a wideband cloaking effect of 2D objects.
