Overlapped illusion optics: A perfect lens brings a brighter feature

Abstract

In this paper, we show that a perfect lens can be employed to make multiple objects appear like only one object in the far field, leading to a new concept in illusion optics. Numerical simulations have been performed to verify the functionalities for both passive and active objects. The conceptual device can be utilized to enhance the illumination brightness for both incoherent and coherent systems. © IOP Publishing Ltd and Deutsche Physikalische Gesellschaft.
