Summary:An all-dielectric carpet cloak, formulated using the optical transformation technique, is presented here. The carpet cloak was fabricated by implementing a dielectric disk matrix (DDM) with varying periods. To demonstrate that it is functional for multiple angles of incidence, the cloak is measured in a near-field scanner. The performance of this cloak is then quantitatively compared to that of a carpet cloak composed of a nanoparticle-loaded polyurethane foam using a novel technique that can be applied to evaluate the performance of other devices.
