Looking beyond the perfect lens

Abstract

The holy grail of imaging is the ability to see through anything. From the conservation of energy, we can easily see that to see through a lossy material would require lenses with gain. The aim of this paper therefore is to propose a simple scheme by which we can construct a general perfect lens, with gain-one that can restore both the phases and amplitudes of near and far fields. © IOP Publishing Ltd and Deutsche Physikalische Gesellschaft.
