hallenrm Posted October 21, 2006 Report Posted October 21, 2006 Science fiction has always dreamt of invisible human beings. Now it seems that these dreams are close to become a reality. A research team, from Duke's Pratt School and Imperial College London, have reported their findings on May 25, 2006, in Science Express, the online advance publication of the journal Science. The work was supported by the Defense Advanced Research Projects Agency. First demonstrated by Smith and his colleagues in 2000, metamaterials can be made to interact with light or other electromagnetic waves in very precise ways. Although the theoretical cloak now reported has yet to be created, the Duke researchers are on their way to producing metamaterials with suitable properties. Theoretically it can made to be possible by allowing electromagnetic fields to essentially pass through a potentially obstructing object. Quote
Turtle Posted October 21, 2006 Report Posted October 21, 2006 Although the theoretical cloak now reported has yet to be created,... Ahh contraire. A working mechanism is extant using microwaves, and in principle a similar technique is possible for light wavelengths.http://news.bbc.co.uk/2/hi/science/nature/6064620.stm Quote
Drip Curl Magic Posted October 21, 2006 Report Posted October 21, 2006 A long time ago, I remember watching a program on the telly about future close combat weapons. At the very end of the program, the idea of a transparent camoflage uniform for soldiers was presented. There was a comment made, suggesting that all the ideas in the program were already being developed. Years later, I ended up finding this video online... of this guy playing with this ball. It was slightly transparents... and he would wave the ball in front of his face, and it would reflect his face on the front of the sphere. Later in the video, the man is outside on a street. and he puts on this jacket.... and his body disappears... reflecting the street behind him. I don't know if this video was a fake or not... and if it was, it was a very well done. Has anyone else seen this video? Quote
Turtle Posted October 21, 2006 Report Posted October 21, 2006 A long time ago, ...In a place far far away...:) I saw several stories on that invisibility technique, but it uses fiber optics and is entirely different than this new method. Check the link I just posted for an explanation.http://news.bbc.co.uk/2/hi/science/nature/6064620.stm Quote
