Via KurzweilAI.net — I’ve long blogged on invisibility cloak technology, but it seems there’s been a real spate of news lately. In fact I’ve already posted the original release for the news in this article.
Here’s the latest:
Active invisibility cloaks could work at many wavelengths EE Times, Aug. 18, 2009 Active cloaking devices can use destructive interference, similar to noise-cancelling headphones, to render invisible areas up to 10 times larger than the wavelength of light being disguised and over large regions of space, University of Utah researchers have found.
The researchers predict that engineers will be able to use their method to create active invisibility cloaks that could shield submarines from sonar, planes from radar, and buildings from earthquakes.
