    "abstract": "We show that a slab of meta-material (with $\\epsilon=\\mu=-1+i\\Delta$)\npossesses a vortex-like surface wave with no ability to transport energy, whose\nnature is completely different from a localized mode or a standing wave.\nThrough computations based on a rigorous time-dependent Green\u0027s function\napproach, we demonstrate that such a mode inevitably generates characteristic\nimage oscillations in two dimensional focusing with even a monochromatic\nsource, which were observed in many numerical simulations, but such\noscillations are weak in three dimensional focusing.",
