The Veselago lens (also known as the super lens) [1], which is a slab made of left handed material with $\varepsilon$=-1 and $\mu$=-1 has interesting properties like perfect lensing [2] and cloaking [3]. When a source is placed in front of it there are regions of high field intensity in such a lens , known as anomalously localized resonant regions [3]. For practical applications of the superlens taking advantage of these properties, the effect of finite loss on the device performance is critical [4] . We calculate the absorption loss of dipole radiation by an $\varepsilon <$0 and $\mu <$0 slab and find resonant enhancement of absorption in the superlensing regime. \newline [1] V. G.
