Design and simulations of dual-polarized mantle cloaking devices

We propose a general procedure to design mantle cloaks able to reduce the scattering of an object for both polarizations at the same frequency. In particular, we analyze the applicability of closed-form formulas available in the literature for the design of planar metasurfaces consisting of rectangular meshes, and validate their applicability in conformal mantle cloaks for cylindrical objects. Furthermore, we propose an easy retrieval procedure useful to refine the initial analytical design and quickly obtain the required surface impedance of the metasurface for both polarizations. Practical examples of dual-polarization mantle cloaks are presented and discussed.
