LIMITATIONS OF METAMATERIALS FOR INVISIBILITY CLOAKING
View through CrossRef
Electromagnetic invisibility cloak (hide) has begun a new period in the scientific community. With the advent of metamaterials and its recent developments, researchers have now turned their faces to invisibility cloak. Metamaterials are man-made materials that have surprising electromagnetic property and it may show the characteristics of negative refractive index in materials that are normally not found in nature in any material. These exotic properties of metamaterial have opened up new possibilities for invisibility and other electromechanical fields. However, although metamaterials have created the field for invisibility cloaking but it has some limitations as well. Specially, constructing a perfect invisibility cloak in the visible range using metamaterials is still a big issue. In this paper, we have focused the limitations of metamaterial for invisibility cloaking beside basic principle of metamaterials and contributions in cloaking.
