Anisotropic cloaking of a metallic cylinder

Abstract

Electromagnetic footprint reduction for a metallic cylinder wrapped in a printed meta-surface is discussed. The meta-surface consists of a quasi-periodic pattern arrangement printed on a homogeneous dielectric layer of constant thickness, which is conformal to the cylinder, giving rise to an anisotropic cloak. Numerical analysis of the radar cross section (RCS) and field topography around the cloaked cylinder for different polarizations of the incident plane wave are considered, and it is demonstrated that the proposed solution reduces the RCS of the cylinder differently for variable incidence.
