Using metamaterials to create illusion and related subtle optical effects

Usage of metamaterial to create illusion and related subtle optical effects is reported. By using the concept of complementary medium or folded geometry, a remote illusion device can be designed, which is capable of transforming the stereoscopic image of an object into an arbitrary illusion at a distance. The illusion device can achieve cloaking at a distance. Finite element simulation (COMSOL) of an illusion device that optically transforms a 2D fish-like object (ε=2) into a star-like object (ε=4) is discussed.
