Abstract :
We show that uniform static currents can be perfectly cloaked by homogenous and isotropic conductivities. These structures, consisting of an electrical insulator coated with a conductive shell with specific geometry and relation to the background conductivity, can make a region of space inaccessible to electric impedance tomography.
