[2]How to turn a narrow slit into a large window
Posted: 29 May 2008 12:34 AM CDT
[3]Narrow slit
How do you turn a narrow slit into a large window? Fill it with a
metamaterial that captures and transmits as much light as the bigger
window. At least, that's what Xiaohe Zhang and colleagues at Shanghai
Jiao Tong University in China tell us.
Metamaterials are substances constructed in a way that gives them
exotic bulk properties that aren't otherwise found in nature, such as
the ability to manipulate electromagnetic radiation in unheard of
ways. Much of the publicity about metamaterials has revolved around
their potential ability to form invisibility cloaks that can hide an
object from view. But less well known are a menagery of designs that
do other strange things such as rotate the appearance of a cloaked
object.
Now Xiaohe Zhang and pals have weighed in with yet another design: a
material "that can transmit the information outside a domain through a
small slit, with the transmittance identical to the one of a big
window". In other word, they've designed a small window with the same
transparency as a larger one, albeit one that works in the microwave
region of the spetrum
But why on Earth would you want one of these? It's one of those things
that has a useful smell about it but the team don't mention any
applications their paper so I'm kinda stumped.
