Abstract

In this paper, full-wave electromagnetic scattering theory is performed to study the illusion and invisibility of inhomogeneous anisotropic spheres. It shows that with the use of a shell designed according to Mie series theory radar cross section (RCS) of the coated inhomogeneous anisotropic object can be dramatically reduced or disguised as another object in the long-wavelength limit. Furthermore, by tuning the anisotropy parameters of the shell, optimal illusion and invisibility of the object are realized. Details of theoretical analysis and numerical examples are presented to validate the proposed methodology.
