Abstract :
In this paper, we introduce "specially-defined" coordinate transformation techniques to produce material specifications which control electromagnetic fields in reshaping objects in electromagnetic scattering (Ozgun et al., 2007), and in reshaping and/or miniaturizing waveguides. We first discuss the design procedure of the anisotropic metamaterials for each application. Then, we present the results of some numerical simulations performed by the finite element method.
