Abstract

Abstract

Properties for metamaterial electromagnetic cloak with elliptical volume under TE wave irradiation are analyzed using finite element method (FEM). Computation results show that 0.5% deviation of the permittivity, permeability and conductivity from the parameters of the perfect cloak affects the electricfield distributions in the outer region of the cloak. The perfect cloak can exclude the electromagnetic fields from the interior region without perturbing exterior fields and therefore the different objects in it can be effectively hidden from to the outer regions．
