title: On the time evolution of the cloaking effect of a metamaterial slab.
abstract: We investigated the time evolution of the cloaking behavior of a small particle placed in front of a meta-material slab with ε=μ=-1+iδ. We found that the dipole excitation would be suppressed in the long time limit. While on the way to being cloaked, the excitation will exhibit oscillatory behavior as the result of the interference between particle-slab resonances and high density-of-states surface modes.
