Abstract

A thin mantle cloak is described for electromagnetic footprint reduction for arrays of thin cylinders. The cloaking is obtained by covering the conformal geometry with a metasurface having as a unit cell that is a width modulated microstrip line. Enfoldings at different angles have been considered and numerically studied both for single and multiple cylinders. Frequency scalability and polarization sensitivity of the geometry has also been considered. Experimental results obtained at K-band are in good agreement with numerical data and demonstrate the applicability of the proposed approach for wide-band (≈ 16%) cloaking applications. The performance of the proposed solution has been compared with available data in the literature, and its superiority has been demonstrated.
