Cloaking an arbitrary object via anomalous localized resonance: the cloak is independent of the object

In this paper, we present various schemes of cloaking an arbitrary objects via anomalous localized resonance and provide their analysis in two and three dimensions. This is a way to cloak an object using negative index materials in which the cloaking device is independent of the object. As a result, we show that in two dimensional quasistatic regime an annular plasmonic structure $-I$ cloaks small but finite size objects near by. We also discuss its connections with superlensing and cloaking using complementary media. In particular, we confirm the possibility that a lens can act like a cloak and conversely. This possibility was raised about a decade ago in the literature.
