It is observed that in frequency at which the effective permittivity of the proposed structure goes to zero, the flat wave front of the plane wave is kept in passing through this structure provided that dipole approximation would be valid. Therefore, with creating a small cavity in the center of the layered metamaterial, the flat wave front of the plane wave is kept and each object which is placed inside the cavity is hidden from the external observer. Finite element simulation using COMSOL Multiphysics approved the result. Using this structure, we could yield the invisibility condition in visible spectrum of 532nm.
