Abstract: Technology has a vast impact over humans. Today we are leading highly sophisticated lives only by its advancement. At the same time it has its own wrong side.
As we are the professionals we should see both sides of a coin. In this paper, we are going to have an overview regarding the worse impact of the technology over humans. Generally materials in nature are in well accordance with the laws of optics. By proper designing of atoms in the crystal lattice of a material using Electron beam lithography technique under Nanotechnology, artificial materials can be synthesized. Thus by miniaturization the general laws of optics (Reflection, refraction and absorption) can be violated. As this violating the laws of nature, its impact sounds more in the wrong side than in a constructive phase. Using such a material we can mask objects of any size from the detectors, just by the proper designing of crystal lattice to be undetectable for a particular band of frequencies. At the worse case we can even mask an aircraft of flying over any restricted spots (parliament or defense organization of a country. Thus even the most highly secured and highly restricted part in the world such as pentagon is at great risk due to the advancement of such technology.
