Abstract

In this paper, we present for the first time a rigorous analytical model of mantle cloaking for cylindrical objects using 2-D sub-wavelength conformal square metallic meshes and patches. The model is based on Lorentz-Mie scattering theory which applies the two-sided impedance boundary condition at the interface of the sub-wavelength elements. It is shown that the analytical grid-impedance expressions derived for the planar FSS grids may be successfully used to model and tailor the surface reactance of cylindrical conformal mantle cloaks. The results obtained using our analytical model for mantle cloaks are validated against full-wave numerical simulations.
