Abstract
A thin metal slab is known to be able to focus the near fields of TM wave of a point source. Here, we show that a thin metal slab in fact possesses a far-field image and through a simple modification on the system by resonance tunneling, a double metal slab can give a bright image with both the far-field and the near-field details.
