Comments on: "Universal Features of Time Dynamics in a Left-Handed   Perfect Lens" by G.Gomez-Santos
  Recently, we have shown the impossibility of perfect lensing with left-handed material slabs, gue to the divergence of the wavefield norm, and hence to the infinite enegy that would accumulate the slab in order to build the stationary state.
