    "abstract": "Utilizing the underlying physics of evanescent wave amplification by a\nnegative-refractive-index slab, it is shown that evanescent waves with specific\nspatial frequencies can also be amplified without any reflection simply by two\ndielectric planar waveguides. The simple configuration allows one to take\nadvantage of the high resolution limit of a high-refractive-index material\nwithout contact with the object.",
