Abstract

Here we present a new kind of 3D display using near zero index (NZI) metamaterial in front of a 2D display. The virtual distance of a pixel is controlled by the refractive index of the metamaterial. As near zero index metamaterials are highly dispersive, a minor shift in the frequency can cause a big change in the virtual distance, hence enabling the control of depth with fine frequency tuning. We derive closed form expression for the virtual distance of a point source in case of lossless isotropic materials and provide a procedure to calculate virtual distance for arbitrary material with given material parameters. A double negative metamaterial working in the microwave regime is demonstrated as proof of the concept.
