摘要：

'Nonlinear invisibility cloak using metamaterial is presented in this paper. To comprehend the said, the notion of point source, cylindrical source, perfect metamaterials and reduced metamaterials are taken for cloaking application. Transformation optics to the metamaterial envisages an interesting variation of both clocking shape and cloaking area with respect to aspect ratio. Simulation results revealed that both cloaking area and cloaking configuration are changed nonlinearly in case of (point source, exact metamaterial), (point source, reduced metamaterial), (cylindrical source, exact metamaterial) and (cylindrical source, reduced metamaterial).
