In 1967 the Russian physicist Victor Veselago predicted the existence of a material with a negative index of refraction, which he termed “left-handed.” He concluded that in the presence of such a ...
Ten years ago, classical optics was but a sleepy backwater of modern physics, a place to while away the hours in the autumn of your career. Then all hell broke loose with the development of ...
Researchers built a silver-grooved chip that channels laser energy into nanometer-spaced peaks, beating the diffraction limit and aiding light-matter studies. (Nanowerk News) Physics is full of pesky ...
Two become one: various diffraction patterns showing Rayleigh's criterion. (Credit: Wikimedia Commons/Spencer Blevin) Scientists have long believed that diffraction limits the minimum distance that ...
A novel imaging technique used for the first time on a ground-based telescope has helped a UCLA-led team of astronomers to achieve the sharpest-ever measurement of a star's surrounding disk, revealing ...
(Nanowerk News) Reporting their work in ACS Applied Materials & Interfaces ("Optically Patternable Metamaterial Below Diffraction Limit"), researchers in Korea report an optically patternable ...
The printable resolution is visible lightDiffraction limitIts value is determined by about 100,000 dpi. However, with such a method of blending a large number of dyes, this limit can not be reached ...
The holographic 3D display is an important technology with excellent application prospects. However, the viewing angle of holographic 3D displays is currently limited by existing strategies. This ...
