Analysis of Uniaxial Multilayer Cylinders Used for Invisible Cloak Realization

Recently, uniaxial multilayer cylinder cloaks which do not scatter electromagnetic waves were proposed. The purpose of this paper is to analyze such structures, and to characterize the achieved invisibility in mathematical terms. For these purposes, an algorithm to calculate spectral – domain Green’ s functions of uniaxial multilayer structures has been developed. The results show that the proposed cloaks work only for the polarization for which they were designed. Furthermore, it was found that, due to dispersion, the achieved invisibility is a very narrowband phenomenon.
