An electromagnetic cloaking device made with composite materials and operating in the range of near-infrared light is presented. The invisibility cloak is designed with transformation optics and consists of 15 concentric rings of different anisotropic two-phase metal-dielectric composites. The anisotropic material parameters of the nanocomposites are expressed with the Maxwell-Garnett mixing rule. The finite element simulation of the concealment produced by the multilayer nanocomposite is discussed. The geometry of the inclusions and the material parameters of the composites are determined with differential evolution-based optimization.
