Making a perfect lens that produces flawless images has been a dream of lens makers for centuries. In 1873, Ernst Abbe discovered a fundamental 'diffraction limit' in optics: whenever an object is ...

Berkeley -- A group of scientists at the University of California, Berkeley, is giving new relevance to the term "sharper image" by creating a superlens that can overcome a limitation in physics that ...

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 ...

Many properties of light are properties of waves, including reflection, refraction, and diffraction. Ch Frame Code Title 1 A Opening Sequence 2 02479 G Light, Electric And Magnetic Field 3 05649 V An ...

Time-varying systems, materials with properties that change over time, have opened new possibilities for the experimental manipulation of waves. Contrarily to static systems, which exhibit the same ...

This video looks at the refraction of light and demonstrates how refraction can make the handle of a Pyrex jug seemingly disappear.

Google Earth provides a cornucopia of exotic images of our planet taken from above. For the most part, the focus of attention is on the land and the cities, roads and natural formations that it ...
