DC Magnetic Cloak
Utilizing a non-resonant graded material consisting of an array of artificially patterned superconducting and soft ferromagnetic elements, a dc magnetic cloak has been constructed. When an external dc magnetic field is applied, we find that the interior of the cloak is completely shielded while the exterior field remains unperturbed, as if the cloak and the cloaked region are just an empty space.
