title: Perfect lens with not so perfect boundaries.
abstract: In manufacturing left-handed media the interfaces will never be perfect; defects and other disturbances to interfaces and material parameters are unavoidable. We report an analytical calculation of electromagnetic wave propagation through a perfect lens with diffuse boundaries. Field localizations are generated in the boundary layers, and the lens' ability to recover evanescent modes in the presence of these boundaries is analyzed and quantified. It is shown that such a diffuse layer produces an effect that is qualitatively similar to a lens with increased losses.
