Latest Material Technology : The Exotic Metamaterial

Metamaterials reveals some of the most interesting properties ever seen in the material and will have the potential to change the industry in a fundamental way . Applications can be very wide ranging from science , information and communication technology , and even the arts .
Metamaterials are artificial materials engineered human technology that has a geometric structure built of materials that can be engineered microscopic . The aim is that the new material can redirect light , sound , and ( another wave ) in a meaningful manner .

Invisible metamaterial
An expert can use the geometry of the material , the size and composition of the material structure to create different effects from the original . One classic example is the use of copper coil array for invisibility cloak on 2D objects so that when illuminated with certain frequencies of electromagnetic waves , such as Duke University in 2006 , the object will be able to disappear from human sight .
The problem with the Duke University in 2006 is that it only works for 2D objects in a single frequency and microwave .
If we want to create something that is invisible to the eye , we need to make it work:
1 . in the visible spectrum ,
2 . in broadband visible light ,
3 . for 3D objects
And in 2012 , has now been able to create a technologist microwave cloak to form the basis of a 3D object . The experts have also been able to make it work on broadband ( ie not just a single frequency but at different frequencies ) . Currently also being tested first metamaterial that will be operating in the visible light spectrum using 15 to 35 nanometers thick layers of silver and hydrogen silsesquioxane (a type of glass ) .
It takes maybe 5 years before we can achieve broadband characteristics , 3D , visual spectrum of the metamaterial that will be used in the normal objects and the human eye . And then 5 more years to figure out how to scale manufacturing to large -scale objects . One idea is to use bio- technology to produce synthetic bacterium capable of printing nanometer coating to the surface of the material to provide scalable and low permeability .

Wave metamaterial for Other Types
Metamaterials derive their exotic nature by interacting with waves in a special way . Apparently, you can also apply the same concept to other types of waves using metamaterials .
You can make a cloak for : radar ( radio waves only ) , acoustic ( hide you from Sonar ) , seismic waves ( which will help you block / drain earthquake waves that enter the building ) .
Most eventually , the metamaterial allows us to hide the object of the most recognizable form of the possibility of a military attack to defense ( hiding the strategic objects and others ) . Nevertheless metamaterial invisibility is not just about the visual – make your building “invisible ” , but also for the seismic wave in order to enter the building design standards in 10 years . Cloaking your wifi / cell network from interference from other networks can improve network bandwidth and reducing latency . Partly also to the cloaking surface of your monitor to reduce eye strain and remove the reflection .

Metamaterial for Super Lens
This is where that would be really interesting , metamaterials can also produce many effects outside the cloaking effect . Depending on , the size of the geometry settings , and the materials used , it is possible to create a super lens that allows us to go beyond the diffraction limit of the normal lens .
Most minimal : make smaller chips through the lens of a high -resolution , super microscope , and mobile phone or camera lenses better . Wireless power transfer is more focused , better satellite imagery , more efficient solar cells , lasers are more focused and are still open to other tools that have lens .
But for the present , super lens technology is still limited to one frequency and not to the visible light spectrum but this proposal has been opened . The next super lens can be applied also to other types of waves , acoustic , seismic and magnetic microphones are very sensitive as well as safe for mobile devices .

Metamaterial for field mechanics
Refractive index metamaterial can reverse light ( illustrations ) , but the latest technology has also revealed that the metamaterial can also be used to reverse the properties of the material outside the optical field ( mechanical characters ) .
For example , when the metamaterial we tap into a piece of elastic foam or bubble , normally , would be flexed into the foam . But the metamaterial , we can make the foam poking outwards towards the direction of the force coming / finger pressure against us ! So the mechanical properties are also inverted . This is a recent discovery made ​​in 2012 . Applications will be very broad include : technology sneakers / shoes are more comfortable , mobile phone casing better that do not break when you drop it , the more efficient wheels for cars and better body armor ( bulletproof armor probably stronger ) .

WIFI antenna the better .
Intellectual Ventures Nathan Myhrvold recently found metamaterials antenna , which will help increase the bandwidth of your Internet connection . Each element of metamaterial antenna can be tuned to direct the radio waves . Likewise , this means a better phone because it saves energy . And on the mobile operator ‘s data transceiving means making more power efficient .

Flips Directions Time
One wild theory is also growing due to the presence of the metamaterial is a process to reverse the direction of time . The point ? As we know , if you drop your phone and then broke apart , little you can do . But with metamaterial , an object can be installed kind blueprint components ( or some sort of technical DNA ) . This allows your phone to reconstruct the original state . Not to re-assemble the components , but the reverse characteristics of the material at the microscopic level .
