A negative index of refraction does NOT mean that light travels faster in it than a vacuum; that formula breaks down for things like this. The true formula is the square root of the permittivity of the material multiplied by the permeability. Either or both of these characteristics can be negative,and depending on the coordinates of the result on the real and imaginary axes, the material will display various characteristics.<br><br>Still, this research is fairly dated. Boo, Engadget.]]></description><dc:creator><![CDATA[Feep]]></dc:creator><pubDate>Dec 20th 2006 10:36PM</pubDate></item><item><title><![CDATA[Comments on ]]></title><link>http://www.engadget.com/2006/12/20/researchers-develop-metamaterial-with-negative-refractive-index/</link><guid isPermaLink="true">http://www.engadget.com/2006/12/20/researchers-develop-metamaterial-with-negative-refractive-index/</guid><description><![CDATA[780nm is not visible light: <a href="http://upload.wikimedia.org/wikipedia/en/0/06/Srgbspectrum.png" rel="nofollow">http://upload.wikimedia.org/wikipedia/en/0/06/Srgbspectrum.png</a> I have an IR-filter in my camera which lets through radiation beginning from 720, which is only a fraction of red light. The filter is totally black.<br>And what is "finer than the wavelength of visible light"? Ultraviolet? X-ray? I thought we covered those wavelengths already. Or did they mean with our eyes? Good luck to that.]]></description><dc:creator><![CDATA[Nelg]]></dc:creator><pubDate>Dec 21st 2006 3:54AM</pubDate></item><item><title><![CDATA[Comments on ]]></title><link>http://www.engadget.com/2006/12/20/researchers-develop-metamaterial-with-negative-refractive-index/</link><guid isPermaLink="true">http://www.engadget.com/2006/12/20/researchers-develop-metamaterial-with-negative-refractive-index/</guid><description><![CDATA[Is it me or doesn't it look like an ancient symbol from the Incas or the Myans???<br>Hmmmmmmm!!!]]></description><dc:creator><![CDATA[Jsmizzy]]></dc:creator><pubDate>Dec 21st 2006 12:31PM</pubDate></item><item><title><![CDATA[Comments on ]]></title><link>http://www.engadget.com/2006/12/20/researchers-develop-metamaterial-with-negative-refractive-index/</link><guid isPermaLink="true">http://www.engadget.com/2006/12/20/researchers-develop-metamaterial-with-negative-refractive-index/</guid><description><![CDATA[Invisibility cloaks? nobody has really thought about this have they. <br>I mean will the sheet of the metamaterial be hiding something behind it or will the sheild itself be invisible? <br><br>so as far as every mans dream goes...   does this mean you walk into the ladies room  cloaked in something that isnt there? <br><br>This may be the star trek age but the clingons havent arrived yet. <br><br>PS : Ive got a whole bag of stuff thats invisible that Im willing to sell. ]]></description><dc:creator><![CDATA[nozzi_na_na]]></dc:creator><pubDate>Jan 1st 2007 9:16PM</pubDate></item></channel></rss>
