  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.
