The development in metamaterial science and technology has created many exhilarating applications from microwave to optical frequency region in which invisibility cloaking is one of the exciting application. In recent years, the RCS reduction characteristics through cloaking structures have been explored by the aerospace researchers, as a novel concept to achieve stealth platform. This paper deals with the design of an ideal spherical cloaking structure in accordance with the transformation optics theory. The performance of the designed cloak is analyzed by comparing the RCS of PEC sphere without cloaking and with multilayer cloaking shells. It has been observed that multilayer spherical cloak shows reduced RCS in C-band with respect to the PEC sphere.
