Two-Dimensional Cloaking in the Visible Frequency Range

Dr. Igor Smolyaninov

BAE Systems

Abstract:   Metamaterials provide unprecedented freedom and flexibility in the creation of new structures, which control electromagnetic wave propagation in very unusual ways. Very recently various theoretical designs for an electromagnetic cloak have been suggested, and an experimental realization of a partial cloak operating in a two-dimensional cylindrical geometry has been reported in the microwave frequency range. I will describe experimental two-dimensional reduced visibility structures, which approximate the distribution of the dielectric permittivity necessary to achive non-magnetic cloaking in the visible frequency range.
