Physicists Demonstrate Flat-Lens Imaging
Jan 1, 2004 — BOSTON, Mass., Jan. 1 -- Researchers at Northeastern University (NU) announced they have been able to demonstrate the unique feature of imaging through a flat lens. Using the phenomenon of negative refraction through a novel photonic crystal, NU physicists observed that a flat slab of such material behaves as a lens and focuses electromagnetic waves at microwave frequencies to produce a real image. The research, published in a recent issue of the journal Nature in the article, "Imaging by Flat...
