Metamaterial and Plasmonic Cloaking

Our seminal proposal for the use of plasmonic materials and/or metamaterials to cloak dielectric or metallic objects relies on a scattering cancellation technique, based the negative local polarizability of cloaks with low electric permittivity.

This cloaking technique is relatively robust to changes in the design parameters, geometry and frequency of operation and we have recently extended it to collections of particles, systems of relatively larger size and multi-frequency operation.

Applications for camouflaging and non-invasive probing and sensing may be foreseen, spanning various applications in medicine, biology, defense and telecommunications. (image right: A plane wave traveling unperturbed through a system of four cloaked impenetrable particles)
