Publication Experimental Verification of Plasmonic Cloaking at Microwave Frequencies with Metamaterials(2009-10-06) Edwards, Brian; Silveirinha, Mário G.; Engheta, Nader; Alù, AndreaPlasmonic cloaking is a scattering-cancellation technique based on the local negative polarizability of metamaterials. Here we report its first experimental realization and measurement at microwave frequencies. An array of metallic fins embedded in a high-permittivity fluid has been used to create a metamaterial plasmonic shell capable of cloaking a dielectric cylinder, yielding over 75% reduction of total scattering width.
