The reshaping technique that is based on transformation optics renders an object to be perceived as if it has a different shape irrespective of the location of the observer. This is achieved by coating the object with an anisotropic and spatially varying metamaterial layer by employing the concept of coordinate transformation. This paper presents a design approach for numerical approximation of reshaper medium by means of concentric layers coated over the object, each of which has simpler and easily realizable material parameters that are determined by the genetic optimization algorithm. The results of various finite element simulations are presented.
