“Metamaterial tiles” are hot in many applications – including invisibility cloak!

By Frank Kuo | Posted: 15 November 2011

Various forms of metamaterial have generated a lot of scientific attention in the past few decades. Some exciting “potential” applications include the well-publicized invisibility cloak (Thanks to Harry Potter). As you may know already, metamaterial gains its bizarre optical property (such as negative index of refraction) by its internal composition or structure, rather than its original physical property. Most metamaterial has its magic only in specific wavelength region and this wavelength region is correlated to how small you can make the internal structures of the metamaterial. This is exactly why almost all the research on metamaterial focuses on THz region since THz has very long wavelength and we do not need to make the structures awfully small to concoct the magic (I did read some articles about “universal metamaterials”, but it seems a long way to go. Let’s dream of that coming in CLEO 2012).
