Contents 1. Introduction
The possibility of the invisibility is revealed by the previous inspiring studies primarily based on the coordinate transformation and conformal mapping [1], [2]. We can use the same Maxwell equations in any coordinate system (either original or transformed one) as long as the permittivity and permeability values are modified. The field lines follow the desired trajectories based on the updated values of the electromagnetic parameters of the new medium. In this manner, it is possible to reshape the incident and exiting light to provide a cloaked region. In this region no interaction occurs between the light and the optical medium. This optical phenomenon is usually denominated as optical cloaking.
