We study the entanglement between two identical two-level atoms located nearan ideal model of invisibility cloaks, by monitoring the the time evolution ofthe concurrence measure. We obtain the reduced density operator of the atomicsubsystem based on a canonical quantization scheme presented for theelectromagnetic field interacting with atomic systems in the presence of ananisotropic, inhomogeneous and absorbing magnetodielectric medium. It is shownthat two atoms, which are prepared initially in an unentangled state, arecorrelated in weak coupling regime via the spontaneous emission and thedipole-dipole interaction of two atoms mediated by the invisibility cloak. Wetherefore find that the invisibility cloak, independent of the hidden object,works fairly well at frequencies far from the resonance frequency of the objectand the cloak, whereas near the resonance frequency, the hidden object becomingdetectable due to a sharp reduction of the concurrence.
