    "abstract": "It is shown that a system of two coupled planar material sheets possessing\nsurface mode (polariton) resonances can be used for the purpose of evanescent\nfield restoration and, thus, for the sub-wavelength near-field imaging. The\nsheets are placed in free space so that they are parallel and separated by a\ncertain distance. Due to interaction of the resonating surface modes\n(polaritons) of the sheets an exponential growth in the amplitude of an\nevanescent plane wave coming through the system can be achieved. This effect\nwas predicted earlier for backward-wave (double-negative or Veselago) slab\nlenses. The alternative system considered here is proved to be realizable at\nmicrowaves by grids or arrays of resonant particles. The necessary\nelectromagnetic properties of the resonating grids and the particles are\ninvestigated and established. Theoretical results are supported by microwave\nexperiments that demonstrate amplification of evanescent modes.",
