CLOAKING WITH GLASS AND CERAMICS
==================================
Using a type of glass that does not conduct electricity, researchers at Michigan Tech and Penn State report discovering a way to capture and route rays of visible light around objects, rendering the objects invisible. Previous attempts to build an "invisibility cloak" have used metals and wires. In the research by Michigan Tech engineer Elena Semouchkina and colleagues, tiny glass metamaterials were arranged in a cylinder shape that produced the magnetic resonance required to bend light waves around an object. These resonators are artificial materials with properties that do not exist in nature, born of the marriage between materials science and electrical engineering. The researchers are experimenting with other materials, such as ceramic resonators, and with other frequencies, such as microwave. The goal is to find applications that work at visible light frequencies, says Semouchkina. SOURCE: Michigan Technological University http://www.mtu.edu/news/stories/2010/july/story29391.html
