Abstract:We introduce electrically thin cloaking devices that deflect a plane wave based on the principles of phase compensation and wave interference. An electrically large perfectly conducting object is cloaked by materials that control the phase velocity of the refracted wave. The design is based on gradient index materials to reflect incident waves in different directions resulting in a significant reduction in monostatic radar cross section. Unlike earlier cloaking devices that were constrained by specific geometr… Show more
