Paper Abstract

We use the chromaticism induced by the resonance of Metal-Insulator-Metal structure and the interaction surface which is greater than the geometrical surface of the nano-rod to combine locally different dimensions of nano-antennas in order to create two optical functions on the same surface. The purpose is to create a phase mask that spread a point source reflected by our system so that at 3 μm this point is horizontally duplicated and vertically at 5 μm. Thus our device changes color information into shape information which permitted another way to differentiate infrared signature of objects.
